Jay Ajayi
It may come as a surprise to some, but this was one of the biggest trades of the 2017 season. The Dolphins sent their running back to Philadelphia in a shocking move. The London-born star earned a Pro Bowl selection for his efforts during the previous season. That’s why it was a surprise when Miami traded the British Ajayi to the Eagles.

Ajayi won a Super Bowl ring with Philadelphia so he’ll be happy with his overall legacy. However, injuries soon took their toll and he prematurely retired from the sport. It’s a shame that he couldn’t keep playing but his body let him down. Unfortunately, that happens to many NFL athletes because football is such a brutal sport (via Bleacher Report).
