It could be true. However, big ben creates a lot of plays by making time with his feet and pump fakes, (of course he takes a lot of sacks and a beating too). Maybe just playing catch Tannehill is better, but until we see him consistently complete the deep ball and until they work more deep passes into the system, we'll have to defer to big ben as a proven deep pass guy.
Consider this...alot of those near miss long balls last year to Hartline would probably be right on the money to Wallace with his speed....we'll see.
