I can live with shaky route running because that can be improved upon (you can be taught proper route running).
The bigger problems with Mike Evans though is that he lack the ability to create separation and doesn't have much speed (I know he ran a 4.5 at the combine, but he looks so much slower on the field). Not too mention how he stayed rough housing DBs. He's gonna get a shytload of offensive PI calls in the pros.
I pass on Evans. Gimme Kelvin Benjamin or Odell Beckham if we're going receiver in the 1st.
