I played for Grant at FL.
My personal opinions of the man aside, the issue the school had with him was he left in the 80's on a leave of absence to coach under Gagliardi at St. Johns. I'd heard he more or less assumed he would be the heir apparent there (because of his last name), but John didn't retire, and Grant had to come back to FL in 1989. He asked for another leave in 1992 and the board said no (justifiably so), so he went to EP.
I can't speak to his first stint at FL (pre-leave), but the 1989 team his first year back was definitely bad. The 1990 team was good - lost in the section final to Anoka who ended up undefeated AA champs. The 1991 team went to state. Not sure about the 1992 team, but I think they were good as well. So the whole hard work thing is BS. I could go into more detail, but I probably ought not.
