He has decent athletic ability and strength but understands how to not get beat, and his overall versatility and experience combine to make him a sixth- or seventh-round talent.
He employs decent footwork in his pass set and when in space pulling. He is a good mirror/shield blocker and doesn't get upfield powerfully very often, but it's rare that you see his man get behind him.
Allen moved to left tackle in 2009 as a sophomore and started all 12 games. He again started every game in 2010 as a junior, playing the weak tackle position and earned Second Team All-Big Ten honors. Allen returned in 2011 as a senior and again started all 13 games at weak tackle, earning All-Big Ten Honorable Mention honors.
Allen has very good starting experience (47 career starts), playing both left tackle and right tackle as the weakside tackle opposite the tight end. He looks the part with average lateral agility, but has disappointing functional strength with very little push in the run game and poor hand use ~ looks like Tarzan but plays like Jane.
Allen has the size and foot quickness to be an adequate pass protector at the next level, but needs a lot of improvement as a run blocker before he's NFL ready. He offers some upside for the next level as a developmental player probably best suited inside at guard or right tackle.
Strengths: A big athlete with good bulk and a filled out frame. Stays balanced and doesn't overextend himself in pass protection ~ stays disciplined with good bend and body leverage. A smooth mover and covers a lot of ground, working hard to mirror rushers ~ agile footwork and keeps his feet moving.
A better-than-expected athlete and has steadily improved in pass protection. Plays with a wide base and is stout at the point of attack ~ can control rushers when he uses his hands effectively. Started the final 47 games of his career with experience at both left and right tackle as a two-year captain.
Weaknesses: Has a sloppy body with a soft belly and very average arm length, not consistently extending his arms. A finesse blocker and lacks an aggressive, physical nature ~ lack of strength exposed in the run game (not a mauler).
Needs to be more aggressive with his hands and jolt defenders at the POA ~ too much of a grabber and catch blocker with poor hand placement. Doesn't have the natural power to redirect rushers and needs to deliver some hits instead of only absorbing them.
Isn't technically refined and gets lazy with his fundamentals, allowing rushers into his body and ending up on the ground too much. Needs to block with better bend and pad level with a bad habit of stopping his feet on contact and slipping off blocks ~ struggles in space.
Needs to improve his overall awareness to recognize extra defenders ~ too many holding penalties for a player with his experience. Lacks an intense, competitive demeanor.
NFL Comparison: Jeremy Bridges, Arizona Cardinals."
-- Dane Brugler
Possesses natural coordination and heavy hands through contact when asked to shuffle and slide. However, is inconsistent with his hand placement and doesn't do a great job gaining inside leverage.
Will allow defenders to fight their way through contact toward the edge and would like to see him display more of a punch/jolt into contact. His natural girth gives him decent anchor strength, but is more of a catcher, doesn't do a great job extending his arm and jolting defenders on contact.
Does a better job keeping his base down in the run game. Looks more comfortable from a two-point stance getting downhill and coming off the football. Works hard to stick through contact, extends his arms well, generates a slight pop and can turn defenders away from the play.
However, allows himself to get upright into contact and doesn't create the leverage needed to consistently overwhelm. More of a sticky player than explosive power/in-line guy. Can be overwhelmed at times on contact when a smaller defender can get under him and will set the edge.
Is quick off the snap, can get around on reach blocks and does a nice job sealing on the perimeter. Plays more like a finesse guy then his frame would lead you to believe.
Impression: He's not an overpowering run blocker, but is smooth and coordinated in pass protection, can keep his base down and warrants a higher grade because of it."
Run Blocking: Allen keeps his lower center of gravity and base down as a run blocker. He is quick off the snap and gets to the second level and reach blocks with relative ease. He does lose leverage on contact a lot. Plays high into contact and loses battles in the run game because of it. I was a little disappointed because I expected him to play with more power in the run game and it didn’t show. He’s more of a finesse guy which doesn’t suit him.
Technique: Biggest technique flaw is poor hand placement in pass protection. He moves his feet well for a big man and has a solid kick slide.
Athleticism/Strength: Allen couldn’t be called an athlete at the tackle position but does well for his frame. He moves his feet well, is coordinated and can reach block well. His base strength is impressive but doesn’t play with power in the upper body. No punch in the run game or in pass protection and needs some strength work, particularly in the upper half.
Bottom Line: Jeff Allen won’t pass many eyeball tests with his sloppy frame but he could turn out to be a solid starter in the NFL. He may be prime for a move inside at the next level. He will need to develop more upper body strength and learn to keep his hands on defenders through contact.
Draft Projection: 3."
Gets in the way and can seal off lanes but seldom generates movement and is exposed by movement.
Can do a better job using his hands and finishing.
Lines up as a weak-side tackle, but projects inside in the pros."
