http://www.dailynorseman.com/2015/3/15/8220467/determining-adrian-petersons-trade-value I'll give you the Rams 3rd round pick for Peterson.
I'm going to be brutally honest, this trade (for jacksonville) is really confusing IMO. Considering the Jags aren't in a "win-now" mode, It makes no sense to trade for a dynamic RB in his older years saddled with a huge contract when there are legitimate needs to fill. Denard Robinson also showed nice flashes last year and you still have Toby Gerhart and Storm Johnson on the roster, so that makes the move all the more confusing. But hey, if you're cool with 2 to 3 possible 1500+ rushing yard seasons with no playoffs, I'm not complaining:grin:
