Lots of questions about Watson's ability to throw all routes and ability to read defenses because of the type offense he ran in college. Its killing his WR because the only 2 routes the scouts say he can run is the back shoulder fade and go route, add that to his questionable speed and not going to run the 40 at the combine. He is a big physical receiver who created separation by pushing off and that will be called in the NFL. But Trubisky has questions too, pretty weak year for qbs.
As for the Browns selecting him over Watson, they also made Manzeil, a first round pick, so they have blew it before.
