Yeah, he should be compared to Mullen because the programs and talent - at least by recruiting metrics - were similar when both those guys took control. The situations were different, for sure, but they both took the reigns of programs that won 4 games the year before.
Some other fair comparisons are the other coaches that took over programs the same year. Chad Morris, Scott Frost and Willie Taggart come to mind.
I think it’s safe to say Pruitt is in the bottom third of that group. Doesn’t mean he won’t turn it around.
