he was successful at Virginia which had been bad for over a decade before he got there. other than that he coached at the parochial school, why do you think he wouldn’t be good at ASU?
Can’t speak for fosternano but ASU is used to getting top recruits from SoCal and Arizona (and doing nothing with them), while Roscoe might be a better at coaching-up players his persona and recruiting shtick may not work for the kind of athletes they are used to bringing in. Personally I don’t know if he’s improved his recruiting style and pitch while at UVa, maybe he’s improved/retooled since leaving Provostan.
