Miami's offense is very predicated on getting the ball into its primary playmakers' hands. They're not like us, where it seems spreading the ball around is a point of emphasis.
If you watch their games, you'll see that the ball is either going to Tyreke, Waddle, or one of their RBs out of the backfield on just about every play.
I mean, Tyreke alone had 1,800 yards, and Waddle had 1,000 in only 14 games.
Look at Miami's target distribution compared to ours. Wilson is third in Wide Receiver targets with a mere 38. For us, that #3 target honor goes to Michael Thomas, who despite only playing in 10 games, managed to have 64 targets.
