Agree to an extent, but the degree to which that's the case depends upon the position. RB, WR, and TE coaches need to be recruiting rainmakers above all else. An OL coach is at the other end of the spectrum -- useless if he's not a great teacher.
Yeah and on top of it all it all has to mesh together. Just look at Wickline's time here. Considered one of the top OL coaches before, completely sucked here, and now is doing well at WVU.
