I don't think Hart will make Hammy's mistake, at least I hope not.
Yes, Hammy did many things that may have helped the bottom line short term, but were really stupid in the long run.
Making the students pay for tickets in spite of already paying an activities fee might have brought in ~ $1M a year, but it was a horrible PR disaster. I thought it was incredibly asinine, for the amount that it brought it.
Basically he gave the university a black eye and probably alienated almost all, if not all, the students just to enhance revenue ~1%. All while he let the product on the field decline.
Penny wise, pound foolish...
And while we did decline from 2001 on, I think the fanbase also grew accustomed to success. 10-3 just wasn't getting it anymore, while in the early 90s it would have been considered a good if not great year.
