I'm not sure it will be, but it's going to be interesting to see. For the most part, prior to last year, I think the Free criticism was overblown. But he did seem to drop off last season.
I feel pretty confident we'll be able to get by at LG with the options we've got on the roster, so if Collins really does come in and play great at LT, it ought to be a big boost to the offense.
I'm not even sure who the offensive whipping boy is going to be. Besides Terrence Williams, of course. It's getting harder and harder to guess.
