Will be interesting TC, and to see how the team lines them up. This is where OTA's are important. They could do the glorified walk throughs, see which players grasps the different line ups.
We know Smith, Martin, Collins
So it will be:
Williams, McGovern (how much do the trust Williams playing basically to a rookie C, I say rookie because he was on IR)
Williams, Biadasz (how much do the trust Williams and in his 3rd year playing next to a rookie C)
Williams, Looney (this may be the best option at first, since lack of OTA's right now) (Vets vs. rookies)
McGovern, Biadasz (doubtful at 1st, as 2 rookies starting without the OTA reps)
McGovern, Looney (I could see this as the 2nd option and vert close to my 1st options of happening)
Not really rooting for a certain combination though. Just put the 5 best out there. And not the best 5 players atheletically, but the best 5 combination to make the offense better.
