We definitely have some solid choices for C and LG. McGovern, Williams, Looney and Biadasz are all big nasties. Still pretty thin at T, but got some horses in the shed at interior o-line.
Because we are so thin at T, I look for Williams to definitely get some snaps there in the off season, enough to prepare him to possibly be the back up swing tackle. If Smith or Collins goes down, our best 5 will include at least 2 of those 4 G/C's. One at G and one at T.
With current rosster guys as Hyatt, Knight and Miller; it's pretty clear Williams is the best option at back up T.
As for starter at C, I think this year will most likely be between Looney and McGovern (probably Looney because of experience).
Williams will still start at LG. The book ends at T are a lock. And of course Martin isn't getting moved from the RG spot, literally.
*Prediction:
Biadasz will be labled by some a possible bust because he didn't follow directly in the beard's footsteps and start at C.
But the truth is those guys will have the edge on him due to NFL strength and experience. Give him a year to catch up and it's gonna be a fight next off season.
