David Yankey OG Stanford #54
Size/Athleticism: Impressive size for an interior lineman. Has long arms. Overall height and length may cause some teams to give him a look at right tackle. Moves fairly well for his size.
Pass Protection: Not really a finisher, and seems to be hanging on for dear life sometimes, especially against bigger defensive tackles. Stays low and uses leverage to to handle the initial pop from stronger interior linemen. Very sturdy base and shows good balance to recover from mistakes or when he’s jolted by an initial punch from a bull-rusher. Rarely finishes off his blocks and often loses control as the play extends. A tough fighter, and often gets the job done even if it doesn’t always look easy.
Run Blocking: Asked to do a lot of pulling in Stanford’s run game and usually looked very smooth and balanced on the move. Diagnoses his assignment quickly and takes efficient angles when working to the second level. Not a finisher. He isn’t the type of road grader that can plow holes when moving straight ahead, but on the move he’s definitely an asset.
Intangibles: Very intelligent player with plenty of experience. Played left tackle in 2012.
Durability: Suffered a season-ending injury in 2010 but remained durable since.
Comments: Yankey will receive a variety of grades from teams depending on their offensive scheme. He isn’t an overpowering blocker but he moves well and should be a nice fit in a zone-blocking scheme. With his lack of power he’ll never dominate, but he can be a quality starter if he’s inserted in the right system which highlights his strengths.
Xavier Su’a-Filo OG UCLA #56
Size/Athleticism: Adequate size, but definitely lacking the dominant size and strength. Fairly quick and capable of getting to the second level. Shows quick footwork. Has the frame to add some weight.
Pass Protection: Does a nice job staying low and getting underneath the defender and using leverage to stand him up and take away momentum. Struggles to recover when a more athletic lineman is able to dip his shoulder and gain a step on him. Awareness is lacking. Late to react to stunts and delayed blitzes and often lunges to recover.
Run Blocking: Quick off the snap but doesn’t have a ton of power in his initial punch. Rarely delivers the first punch that knocks his assignment back and, at best, usually plays to a stalemate. Not a road grader who can clear space. Capable of getting to the second level but gets lost in space. Doesn’t always quickly identify his assignment at the second level and wastes steps trying to locate and pin down the angle to take.
Intangibles: Three-year starter. Leaving school after junior year. Will be a 24-year-old rookie. Served a two-year Mormon mission from 2010 to 2011. Has some experience at left tackle.
Durability: Started all 40 career games.
Comments: Su’a-Filo has a decent blend of strength and quickness but he isn’t elite in either area. He appears to have the frame to add some weight and would definitely benefit from improving his power. He fights extremely hard, but he rarely finishes off defenders. As of right now, he’s a bend-but-don’t break blocker in pass-protection and struggles to clear space as a run blocker. His run blocking grade may vary greatly from team to team. He’s probably better suited for a scheme that will utilize his athleticism, rather than a power-run team.
Zach Martin OL Notre Dame #70
Size/Athleticism: Lacks ideal height. Athleticism is only average for a tackle, but quick footwork would be an asset if shifted inside to guard. Seems to struggle with balance, which especially hurts his play in pass protection at tackle. Short arms, especially for a tackle, and it shows up in his game.
Pass Protection: Lacks the long arms and elite upper body strength to swallow up defenders and completely take them out of the play. Once he’s engaged, he battles hard but he’ll the battle on occasion. Looks awkward trying to slide outside with edge-rushers. He’s fundamentally sound but he just isn’t quick enough. When the outer limits of his ability to kick out are tested he looks awkward and tends to get upright and out of position. Fairly strong lower body allows him to handle himself the bull rush, but it’s a challenge and he often loses leverage as the battle goes on.
Run Blocking: Not strong enough to be a dominant road grader but is technically sound and can be effective. Quick off the snap and delivers a nice initial pop. He’s a fighter and always plays through the whistle. Shows great awareness and doesn’t get lost in space. Looks fluid getting to the second level. Takes smart angles and diagnoses his assignment quickly. Lacks the mobility to adjust if he’s attacking a moving linebacker in space.
Intangibles: Plenty of experience as a four-year starter. Team captain as a junior and senior.
Durability: Started 52 games with no known issues.
Comments: Martin is a smart lineman and technically sound in all aspects of the game. But he lacks the athleticism to play tackle in the pros. My biggest concern is his lack of balance, which really showed when facing more powerful edge-rushers such as Ziggy Ansah. I think most of his flaws can be masked at guard, because he can handle bull-rushers, he simply lacks the ability to handle the dominant punch delivers from strong edge rushers who can build momentum before engaging. That said, his power is still a concern and there are too many questions to warrant a first-round selection.
Joel Bitonio OT Nevada #70
Size/Athleticism: Lacks ideal height and overall frame. He’s little on the light side and doesn’t have the dominant strength to overpower anyone. Arm length isn’t great but perfectly adequate, especially for his size (same length as Taylor Lewan). Impressive quickness. Tested well in agility/speed drills at the combine. Some teams may view him as a better fit at guard.
Pass Protection: Elite footwork and quickness allows him to slide outside with faster edge-rushers. Uses leverage to his advantage to hold his ground against bull-rushers. Shows great awareness on the field. Quick to react to the movement around him. Once he’s engaged, he’s already won. Very tough to shed his blocks once he’s locked in.
Run Blocking: Does a nice job working to the second level. Shows good awareness in terms of locating his assignments and gets there quickly. Quick enough that he can adjust to the movement of the linebackers at the second level. Plays with a nasty demeanor, always fighting through the whistle which helps him overcome his modest strength and power.
Intangibles: Played extremely well against his toughest competition (faced Florida State and UCLA in 2013). Clearly a tough competitor who gives his all on the field every play.
Durability: No known issues.
Comments: Bitonio doesn’t have the elite measurables, but he does everything necessary to make up for his modest size and physical tolls. He’s an impressive athlete, which could attract certain teams to him (Chip Kelly’s offense would be a great fit). Any team willing to overlook his height and focus on the total package may get a steal.
Antonio Richardson OT Tennessee #74
Size/Athleticism: Massive frame and has the ability to swallow up defenders. Surprising quickness for his size and is capable of getting to the second level.
Pass Protection: Fundamentally sound. Quick out of his stance and his impressively quick footwork when sliding outside considering his size. Has long, strong arms and can lunge after an edge-rusher who gains a step on him and still throw him off balance enough to recover. Shows impressive awareness and seems to diagnose blitzes before the snap. Adjusts quickly to stunts on the line and delayed blitzes from the second level. Struggles to stop the second effort if the lineman is able to disengage from the block.
Run Blocking: Quick out of his stance and delivers a devastating initial punch. Easily drives his man back and finishes off blocks. Takes proper angles and shows good awareness when getting to the second level, but lacks the mobility to react in space. If he isn’t beat off the first step, he’ll win the battle but he does get beat by the elite athletes (Clowney had a few plays where he was simply too quick off the snap for Richardson to handle).
Intangibles: Two-year starter at left tackle. Transferred high schools due to academic reasons.
Durability: Underweight knee surgery in 2013.
Comments: Richardson has all the tools that you can’t teach. It’s easy to notice his size, but his quick footwork and balance is just as important and impressive considering his size. He definitely has some flaws in technique and may be a risky starter as a rookie, but his flaws are coachable.
