There's no great mystery preventing a great DII coach to make the jump to DI. Many DI programs have alums and many candidates lined up for a tennis coach opening. If he's making 80k at AA that confirms my suspicion that pay to make the move has to be an issue. 90k+ jobs in college tennis are hard to come by, the exception not the norm and heavilly competed for. He's probably happier than we know right where he is.
