Gard was an interim that year. He makes about $2MM. Few is underpaid, but seems cool with it and Gonzaga is not a P5 program. Mack is also not at a P5 program (and like Gonzaga, no football media revenue) in a Xavier job that's been a stepping stone. He's a legacy, though, so I could see him being like a Few and coaching long-term for below his market value.
Anyway, Tad is not overpaid. If we brought in anyone else of Tad's level in the basketball coaching world it would probably cost in the $2.5MM range.
Did you want to talk attendance and why that changed? Because it had almost everything to do with a change in C-Unit leadership, a change in the AD, increased ticket prices, and a Pac-12 scheduling scheme for tv friendliness instead of live fan attendance. You're blaming Tad?
