Unfortunately, if it's going to be more than 2 months, they will IR him. No sense in rushing him back when he could easily re-injure his knee.
I think the line is better than last year, assuming no more injuries. Starks will be alright until Adams takes over and Gilbert has a year of experience who is better than Colon at RT...and Colon will be better at LG than anyone in recent memory. I just hope Gilbert stops falling on people. Anyway, a lot (not all) of the beatings Ben takes are of his own doing by holding the ball too long and everyone here knows it. I'd like to think Haley will have Ben throwing sooner which will help Ben and the line a lot. Sure, there will still be plenty of times where Ben will try and make plays and take hits, but I'd like to think it will be quite a bit less than years past.
We need Mike Wallace back! Even if Ben doesn't have enough time to wait for Wallace to get down field, Wallace will be double covered allowing Brown and others to get open just like the second half of last season.
