ESPN beat writer James Walker:
Dolphins RB Jay Ajayi started just 12 games last season and put up huge numbers. This is the first season entering as the known starter and Ajayi has more confidence and swagger that he can carry the load. Dolphins head coach Adam Gase said he won't be afraid to give Ajayi 350 carries if needed this season. Ajayi also has worked diligently on catching the football out of the backfield, which to date is his biggest weakness. Ajayi should have a monster year and could put up 1,900 total yards if he stays healthy.
Ajayi had a breakout season, but nearly 58% of his rushing yards came in four of his 15 games (against the Bills twice, the Steelers and the Jets). He averaged 6.74 YPC in those four weeks, and just 3.56 YPC in the other 11 games. Not coincidentally, three of those four big games came with center Mike Pouncey in the lineup, yielding a 5.96 YPC with Pouncey (versus 4.12 YPC without). As long as his offensive line is healthy, Ajayi should have a very productive 2017.
