Giants were terrible and might have won a game or two at most without Barkley, he *was* their offense this year.....and he made that impact from the rb position. Is Saquan Barkley the best rb in football now? It's very arguable, and several pros, HoF'ers, coaches etc have come out and said he's already the best back in the league... as a rookie.
If I had the luxury to be given any RB in the NFL right now it would be him without hesitation.
Crazy stat I read: the most receptions as a rookie for *any* position in NFL history was Anquan Boldin with 101 as a wide receiver, and after this past game #2 is Saquon Barkley who tied his teammate Odell Beckham Jr with 91. That's on top of 5.0 yards per carry (tied with McCaffrey for highest in the NFL for 15+ carries/gm) and 2,028 all-purpose yards (also #1 in the NFL).
If anything he and Baker are both equally deserving, but I think Mayfield won because a) QBs always get more love and b) Saquon was on a team that hasn't been the running joke of the NFL for the last 20 years which definitely helped Mayfield.
