The overlooked fact is Casey Dick WAS A BETTER QUARTERBACK than Mustain. Here's their stats from that year.
PASSING GP Effic Cmp-Att-Int Pct Yds TD Lng Avg/G
--------------------------------------------------------------------
Casey Dick 10 125.72 65-132-6 49.2 991 9 50 99.1
Mitch Mustain 12 120.53 69-132-9 52.3 894 10 70 74.5
Notice that on the same number of attempts, Dick had 100 more yards, a better TD-INT ratio and a better passer rating. Not to mention that, from all appearances, Dick was a better leader than Mustain. And Coach is right when he said that Dick is head and shoulders better than any QB we have right now. I'd add that he's also better than any we've had this century.
