The Miami Dolphins made major changes to their franchise last year by spending big in free agency by adding players like Terron Armstead, Chase Edmonds, Cedrick Wilson and Connor Williams. In addition to that, they hired Mike McDaniels as their head coach and made the huge trade for Tyreek Hill. Those moves paid early dividends as the Miami Dolphins jumped out to an 8-3 record. However, the team struggled down the stretch, even after making a trade for Bradley Chubb around the trade deadline, and only won one of their last six regular season games. One of the big reasons for their struggles was the absence of Tua Tagovailoa, who suffered a second concussion of the season against the Green Bay Packers in Week 16 and missed the remainder of the year.
