I just do not believe that staff projects the next year's starters, as you imply. Cooper will likely be back in 2018 (could decide to move on) and it would not be surprising to see an OLB move to MLB as has been done frequently. I am more inclined to believe the staff strictly redshirts based on the current year's potential contribution to this year's wins, and CJF has stated as much. Getting a few actual game snaps is not that much of an advantage, especially given that We have such a solid 3 deep at MLB for 2017 (Cabinda, Smith, Cooper). Brooks, coming from H.S., will get plenty of development in practice and on the foreign team this year.
It would take 2 MLB's going out of an extended period for there to be a legit reason to play Brooks in 2017. And that would also depend on if he is really ready. Brown was not really ready when he was forced to play in 2016, but we have greater depth this year, and a move of one of the OLB's in side would be another option to deal with 2 MLB's getting hurt.
