The AFC is going to be tough this year after the many additions that the teams made to their rosters. Yes, the Miami Dolphins are one of those teams that got better when free agency hit but are the additions of Terron Armstead and Tyreek Hill enough to compete with the firepower at the top of the AFC? How well the Dolphins do this year will most likely come down to the play of Tua Tagovailoa, who is entering his third year. Mike McDaniel was brought in to get the best out of the young QB and with the additions of Armstead and Hill, it’s hard not to believe that Tua could take a huge step this season.
