I'd prefer Briles over Dorsey if I was making the hire. Give me the proven commodity that has called a Top 10 College offence.
I've no doubt Dorsey knows his Xs and Os, but he's been a position coach for 8 years. It doesn't take that long to get an OC job in the NFL if you're highly though of - look at Moore in Dallas, look at McVay with the Redskins and obviously look at Brady with the Panthers.
I hope he gets whatever job he wants in the offseason - if it's ours, great, but I wouldn't talk down someone like Briles just because he never played for us.
