Miami Dolphins quarterback Ryan Tannehill has been one of the best players in the preseason. He's thrown three touchdowns and has a 121.8 passer rating in his three preseason games.
The Dolphins have improved their offensive line and they no longer have receiver Mike Wallace, who rated out as one of the worst receivers in football, per Pro Football Focus. For the stat nerds, check out his route chart (per Pro Football Focus):
That's not good, having a passer rating of 59.6 on passes to Wallace last season. OK, tangent over. The point is Tannehill is really set up for success. He has a better tight end in Jordan Cameron, and a full offseason with Jarvis Landry bodes well, too. Plus, he has Kenny Stills to stretch the field.
Fantasy impact: Tannehill is the 11th quarterback coming off the board right now, but that might change. Check out his ADP graph from Fantasy Football Calculator:
As you can see, he's seen his ADP rise by a whole round this week. If you miss out on the big guns like Andrew Luck and Aaron Rodgers, Tannehill could be your man.
