now ur tripping, Tate is just as mobile as both of them. He is definitely more mobile than Baker and is just as mobile as Manziel. That being said I do agree with your statement on Tate's arm strength.
That 2 years don't mean ****, all of them are learning a new offense, and if you talk about the QB coaching received these past 2 years, I would say Tate had the better coaching, while the other 2 were coach by lil Richt.
