It's going to be hard to supplant Austin, but given that we have a crush on Brown, he's probably the one most apt to lose a spot. Which kinda works out, because Smith and Johnson are both more of that type. No idea if Smith can return punts though.
Pollard can supplant Austin in the base offense, while Wilson can take the punt returns.
I'm an Austin fan, but Pollard is the future for an on the field speedy run complement to Zeke. Austin is the developmental bridge for Pollard. Pollard may be across that bridge already.
It would be awesome if we can go with Wilson and Smith, and have WR set through #4 for next year.
I was really hoping that McGovern could start this year at LG, Williams would move to RT, and we'd have our starting oline set for 3 years.
But the offense looks very set for the near future. Next year's draft can be a defensive one.
