It's do or die for the Miami Dolphins this season. If they can't turn things around and at least earn a spot in the playoffs, it could be the end of the current regime. They've made a few aggressive moves in recent months, but there are still some glaring holes on their roster.
Recently-unretired Darren Waller is set to be Miami's starting tight end this year. He's nice to have on the roster, but it's hard to trust him to perform at a high level, especially early in the season. The Dolphins could use an upgrade at the position in a big way.
