With only 5 scholarship DE's ahead of the true freshman I expect one of the true frosh DL kids to play. Linemen get nicked up and CJF likes to substitute freely to keep his DL fresh. I expect either Carter, who can play DE and DT, or Buchholz (DE) to play this year. 5 DE's seems like a lot, but it's a long season and it's critical to have fresh D linemen in the 4th quarter of games to pressure the QB.
Also agree that at least one of the WR's will play. But putting all 3 of them "yellow" is a good call because who know's which one or two will play?
