Cannot deny that he's done that. And because of his athleticism he probably got away with that move from the time he was playing pee wee straight through college. NFL DC's will eventually take that away from you as soon as they recognize that it's your go to move. A good HC/QB coach/OC will coach that out of a QB, so what is it? I think some of it is habit. you always revert to bad habits under pressure. I've bowled semi-professionally my whole life & bad habits creep in when I'm under the gun to make something happen & I have worked on eliminating those habits for 30+ years lol. I do believe that the coaching that Murray has received hasn't helped either. So, bottom line, it's a combination of all three. Bad habits, poor OL, poor coaching. Hoping that better coaching, better OL, and Murray working to eliminate that spin move altogether (he doesn't do it nearly as often as he did in years 1 & 2) can help him moving forward.
