Dolphins trading Ajayi is absolutely ludicrous. Shit makes no sense to me. Dude had an attitude problem, but so did Vontae Davis when we traded him. Next thing you know, he's in the Pro-Bowl.
Young players often have attitude problems. They also tend to grow out of them, as being a douche is socially and professionally maladaptive.
Eagles backfield is going to be deadly now. Ajayi will kill it behind a competent offensive line. The cartilage in his knees has degraded to the point where it is basically bone on bone already, so he won't have a long career, but for a couple of years Philly will have one of the best running backs in the NFL, at the cost of a 4th round pick.
