If a QB hits on 50% or more (including drops), he has an exceptional year. Only 3 QB did it last year, Rodgers, Peyton, and Newton. This year there are only 2 in Rodgers and Wilson.
Last year Tannehill hit 22 of 51 (including 2 drops). IF you believe he should hit 50%, 25 throws should have been incomplete. When you add this to the 22 passes he hit on, it would leave FOUR passes during the year to be questioned.
This year Tannehill hit 12 of 34 (including 3 drops), 17 should be incomplete. Added together, it would leave FIVE passes over 10 games to be questioned.
One may consider the WR's from last year, and the sacks along with some mistakes from Wallace this year or, question NINE passes over 26 games if you believe Tannehill should be exceptional in his second year on deep throws with this team.
