McCants was actually playing the tuba in the Williamson High School band before joining the football team as a senior. Despite the lack of experience, he started seven games as a true freshman. After sitting out the 2008 season due to academics (he carried a 1.7 GPA), he regained his starting left tackle spot for every contest as a junior.
Because McCants has little experience, teams will overlook his inconsistent knee bend and kick-slide because they know his size, athleticism and footwork give him a chance to succeed in the pros whether at left tackle, right tackle (where he lines up on occasion) or even guard. Continued improvement will only make scouts covet his upside even more leading up to the draft.
Pass Blocking: Strong pass protector with length to play at the next level. Quick enough to pass off twist and pick up late blitzers. Size and length allow him to carry pass rushers around the pocket. Extends with a punch and locks on with strong hands, defenders won't chop off to disengage. Anchors well despite his height, absorbs punch into his chest and maintains his balance. Inconsistent posture, stands straight up out of his stance then will bend at the waist on occasion, gives up inside lane when technique falls short. Needs coaching on maintaining his knee bend and lateral slide, will cross his feet when facing speed.
Run Blocking: Plays with some power in the run game, moves his legs after contact to push the pile. His positional blocking is most impressive, uses strength and footwork to get to either side of his man. Capable cut blocker despite his height, lays out to knock defenders off their route.
Pulling/Trapping: Gets out of his stance adeptly, moves well out in front of outside runs and usually finds a target to wall off. Fails to see inside defenders at times, allowing penetration.
Initial Quickness: Typically gets out in front of pass rushers and comes strong in the run game, though his height and length allow him to get out-quicked at the line on occasion.
DownField: Gives good effort to reach smaller linebackers and take them out of the play. Stays with the block throughout the play. A bit slow finding targets at times, and lacks quick-twitch ability to adjust to quick defenders in space."
He does a nice job extending his long arms into contact and is very coordinated with his punch with asked to slide and punch. However, in order to anchor vs. bigger defenders, he will widen his footwork in order to overcompensate and loses his balance/footing in the process.
He exhibits the range off the edge to routinely reach speed off the corner and he's a natural bender who can sit into his stance, keep his pad level down and look very fluid sliding his feet laterally when asked to mirror both in space and through contact.
He's balanced into contact with his punch and does a nice job keeping his weight evenly distributed in the pass game. He also exhibits the range and mirror ability to hold his own on the left side at the next level.
McCants exhibits elite range when asked to pull and get out to the second level. He is very coordinated in space, moves effortlessly and has the flexibility to cleanly drop his pad level and cut down defenders on contact.
He coils up into his stance well and exhibits a good initial snap through the hips into contact, extending his arms well off the ball and initially gaining leverage. He moves his feet in order to mirror and maintain his angle.
However, he will begin to pop upright through contact, limiting his natural power and taking away from his push and ability to stay engaged through contact.
Impression: McCants possesses a great looking frame that has the ability to get bigger and mature physically. Athletically, all the tools are there for this kid to play left tackle in the NFL, he just needs some time to make the jump in competition and mature physically."
Run Blocking: McCants is a good athlete that excels when asked to pull or get to the second level. An above-average move blocker with superior coordination in space. Needs some work in terms of leverage as he has a tendency to stand up through contact. He isn’t a drive blocker because of the lack of lower body strength but could develop with added bulk.
Technique: Long arms, big hands and is tough to break free once engaged. His footwork is solid with no major issues. He does get lost at times on blocking assignments but should get better with a good OL coach. Has to break the tendency to get wide against power which causes him to lose balance.
Athleticism/Strength: McCants is an above-average athlete at the position that has a ton of room to grow. He showed up at the Senior Bowl at 309 from his reported playing weight of 295 at UAB. McCants has the frame to max out at 315 easy without losing anything in terms of athleticism.
Bottom Line: McCants may not be an NFL ready LT but he is one of the few tackles in this draft that has the look of a blindside protector. That in itself should have McCants higher than most expect. He needs some refinement but with good coaching he could develop into a nice starter in the league.
Draft Projection: 3."
Inconsistent technique — is tight in the hips, tends to lock his knees and play upright, negating his anchor strength.
Lacks awareness and can be short-circuited vs. the blitz.
Needs to add bulk and improve his playing strength.
Is most ideally suited for a zone-side protection scheme.
Comparable to Bills OLT Demetrius Bell, a seventh-round pick in 2008."
Has long arms and light feet and is an excellent pass blocker who can cut off the edge; also has a natural bend and can change direction; quick off the snap in the run game and does a nice job sealing off defender, but doesn’t get much push as he will struggle to keep his pads low;
Also needs to get bigger and stronger; did not play in 2008 because of academics and missed spring practice this year after undergoing off-season shoulder surgery.'
He is not completely filled out and is a couple years away from reaching his full girth.
His great hand-eye coordination gives him a great punch while sliding out into pass protection.
McCants has great range in establishing an edge or if asked to block on the second level.
For a man his size, he moves tremendously well.
When he caught out of position, he needs to learn to stay disciplined through his techniques and keep his natural bend.
That said, NFL scouts are going to be all over this young man when they see him in person during pro days and the NFL combine."
