Like all drafts, we start with our normal picks. We keep guys based on where they were drafted this past year or the year before (keep players for max of 3 years). Anyway, RGIII and Thomas both drafted in the 3rd round. I don't have two 3rd round picks, so one of the guys could be kept at a better pick (next best pick is the 2nd round).
Gotcha. Then I would keep RG3 for your 3rd round keeper, and then I'd try to trade Thomas for guy that is promising in return. I would look for a guy that's in a similar situation as you who has two good players from the same round. Or see if you can find a with multiple young stud RB's (Martin, Spiller, or Charles). Charles may be a steal if the guy drafted him late this year due to his injury concerns. But honestly, I don't know how long Decker will be a bonafide number 2 WR, but it's worth a risk. After all, Manning hates change at WR. Also, as much as I like Denarius Moore, there's no telling what happens to Oakland's QB situation next year, if they go with a rookie, that might be bad for Moore's stats for the next couple of years.
