All very good players, but as i state all players are A potential grade. Scandrick and Jenkins are B grades.
Robiskie's speed was why he didn't make my list, if u check the players on the WR list they're all Speed WR's, which is what matters in Madden, maybe after a few seasons his speed will increase, I could of added a lot of WR's to the list but I just looked at Age, Potential and Speed for WR's!!!
I dont have any issues with the players you've chosen, I just needed to narrow the list down. and I would always go for speed over slower and A over B in my trades!!
