CWill was probably better than most would have people to believe on here, same for Collins. As they need to pile on once it gets started.
Anyway, CWill in his 2nd year and stronger, will be better. Plus player between Smith and Frederick will make any player look better. So CWill will be just fine there.
Collins, as you said at best is above average, but he is certainly not horrible. If the left side and up the center is solidified, they can always have a TE over to help Collins on the right side if needed. If teams load up that side. I would hope they learn from the Chaz Green Atlanta game debacle.
