I think Sweezy starts, and I am actually really into his upside.
There were mistakes, no doubt about it. But his "losses" weren't due to being physically outmatched, they were do to seeing things for the very first time: be it a pass rush move by Darnell Dockett, a T/E stunt, or foriegn fronts and blitzes. The same mistakes were rarely made twice.
The kid is clearly able to attack and take on a learning curve, just by being able to get on the field and start after the position change speaks to how quickly he can pick things up. With Cable teaching him, and his capacity for learning he'll just become more and more aware. For example, if you can watch the 2nd matchup with the Cards, do it. He absolutely dominates Dockett the 2nd time around and on way play took Dockett about 7 yards downfield against his will.
I see a kid whose movements skills and athleticism totally standsout. A guys who carries that size naturally given his strong jawline, long muscular arms and slimmer waist compared to the majority of olinemen around the league with "dumpy" builds. I think Sweezy can get up to 310lbs and still look chiseled. I also liked how in the Cards beatdown there was one posession when the Hawks were up about 50 and the entire Cards front 7 seemed to be pissed at Sweezy - so Sweezy dropped a heatbutt on Washington knowing that 15 yards doesn't matter in a blowout.
A couple examples of why I am so bullish on Sweezy. His combo of both bigtime movement skills and raw power in the run game.
Watch him just plow, turn, and pancake this Falcons starting DT in the playoff game at 9:40 of this video http://www.youtube.com/watch?v=eMhESn1cyV4
Here, bigtime movement skills. Patrick Willis clearly isn't ready for an interior lineman that can get to the 2nd level and cut him down this quickly. At 10 seconds.http://www.youtube.com/watch?v=Ir3Qd1MqgzY
Those two plays would have been bigtime from David Decastro as a rookie, nevermind Sweezy.
Sorry to hijack but I saw some knocks on Sweezy in this thread ( hell, someone referred to one of the Hawks as an "arse clown", anonymously of course).
Kris Dielman made the DT to G switch and didn't start a game until his 3rd year. Sweezy is destroying the learning curve.
