I would rate the three RB's:
1. Peterson
2. Turner
3. Lynch
I don't understand why some people want Lynch to be the pick at #12 but wouldn't give up a first round pick for Turner.
I know...I know...you may not think Turner is better than Lynch, but he is more proven in the NFL than Lynch.
And I am not suggesting trading the #12 pick straight up to get Turner, but I would not lose sleep if the Bills and Chargers exchanged 1st round picks.
ALTHOUGH.....I would say, by all means,...if they can get Turner for a cheaper price....go for it.
