For college football and to a similar degree for men's basketball, there is no such thing as too much. At some point, whether sooner or later, 'no too much' can become a major problem. The 'much' refers to money as it envelops a college sports world in which hundreds of millions are now spent on annual rosters with only the slightest relation to financial return on investment.
The money explosion affects many college basketball programs as well. Other college sports are also impacted. Without NIL funds, Texas Tech Softball and a $1M pitcher probably would not have made the Women's College World Series Final.
