Some segments of the football world were outright shocked when the Dolphins flipped running back Jay Ajayi to the Philadelphia Eagles for a mere Day 3 draft pick prior to the trade deadline. After all, Ajayi is still a young back who rushed for over 1,200 yards in 2016 with several outright dominant games along the way. Perhaps most puzzling was that Miami didn't appear to have a direct replacement on the roster. As it turns out, they may not have just had a replacement for Ajayi waiting in the wings, but a tangible upgrade.
