Well let's see.
1 - He's coached two full seasons, with two Regional appearances. Lost to the host seed in the IF championship game both times.
2 - He's only been to one BR Regional, his first season where he took over a depleted team that the previous coach tried to burn down on his way out, pretty much down to the IF game vs. LSU.
We should probably at least allow this second visit to a BR Regional to play out before we say his "MO" doesn't work.
ETA: I did see your reply below the above quoted comment. Maybe he does need to ride an ace for a whole Regional and see how it goes, but I'm more than willing to sit and see if second time around his strategy can work. In the past years (last season, which was cut short, being the exception), we've only had one real post-season starter to ride.
