How about Mark Duffner? This guy won big at the DIAA level. In six years at Holy Cross (not the easiest place to win), he compiled a 60-5-1 record for an astonishing .917 winning percentage. That included two perfect seasons. So what happened to this rising star when he took his scheme and program to DIA and specifically the ACC? He bombed. In five seasons at Maryland he went 20-35 with a .364 winning percentage.
Let’s look at another New England DIAA product whose success included a stop in the Ivy League. Buddy Teevens only spent two seasons in Maine but he improved the team each year finishing with a 13-9 record and a .591 winning percentage. He then moved onto Dartmouth where he only had one losing season and finished with a 26-22 record and a .541 winning percentage. (He has since returned to Dartmouth.) So what happened when he got his shot at DIA? He stunk up the joint at Tulane going 11-35. Even his second chance at Stanford was a disastrous 10-23.
So again, Mark Whipple may have succeeded at BC. But he was far from a sure thing.
