Def not going to do it for Sproles. But I did sell J Charles for 10k... Just depends on certain factors. Speed sells high I've noticed. Don't have the stats in front on me but I'd maybe value 91 Sproles higher than I would 96 Carter. When looking at stats, that card has not once moved me to action. I tried to bid on him at 1500 once but that was just to try and turn a quick profit.
