I don't know who the 2nd guy is, but LeRon McCoy is on IR. He was pushing BJ for the 3rd spot until he got injured. He a better fit than BJ for that 3rd spot, because he's one of the fastest players on the team.
Another thing. There are several threads (including this) on re-building the OL, and I'm puzzled over some of the comments.
Leinart is left-handed! That means that our blindside OT is the RT - NOT the LT! If we draft Joe Thomas etc., he would become the RT!
Wells has great feet and is a "finesse" O-Lineman. He only fits two positions in our scheme. C and RT (the blindside OT). He would NOT Fit at LT (the frontside)
Speaking of the frontside. Have anyone noticed how Big has settled in over the last couple of games. On paper, there's isn't that much difference between the front and blindside OT, BUT the mental pressure is much, much bigger on the blindside, because that player can't miss a block - EVER!
Big has had some of that pressure taken away from him and defenses cannot bring the same pressure anymore, because Leinart is getting better at beating the blitz. Big has been playing very well, since he became the frontside OT.
And what's this talk about moving Milford to C. First, isn't he playing pretty well at LG? Second, C is a more technically difficult position than G. I wouldn't exactly call Milford a finesse O-Lineman. He's a mauler, so why not keep him at the #1 mauler position (frontside G), which is where's playing right now.
