It's not a mid-major roster. Just because many of them started and/or were recruited to play at Drake does not mean they are simply mid major talent now. He's a good coach - he's not that good of a coach.
Some examples:
* Diego Pavia, Vandy QB who was named SEC offensive player of the year and was runnerup for the Heisman, was a ZERO star coming out of high school. He spent two years in junior college. So is he still a zero star?
* And then there's Mr. Stirtz, of course.
* John F. Kennedy was a poor public speaker as a young man. By the time he was president, and still pretty young, he was one of the most eloquent public speakers of the 20th century.
People often improve their skills--sometimes dramatically.
There are great professors and great writers and great coaches working far under the radar. That doesn't mean they couldn't be teaching at Harvard or churning out best sellers or turning one of the worst college football programs in the country (Indiana) into a BIG champion and national title contender if given the opportunity.
