Nobody said it has to be a Ram
I'll go with Nick Foles. I think he is a top 3 pocket passing QB in the NFL. Last year, his stats projected over 16 games (he only played in 9 or 10) were second best in the NFL.
If we are talking about just Rams then I go with Ogletree. He can be one of the best LBs in the NFL if he continues to be a turnover machine and gets more sound with his tackling/run defense. I love watching him play, he was my favorite player on defense last year. He has the speed and ability to match the division foe play of Daryl Washington and Bobby Wagoner. I hope he does.
