Your argument is that high profile players should get paid. Your example was Texas A&M and Johnny Manziel. One of your points was that donations for the school tripled because of Johnny Manziel.
their qb's success had everything to do with it. he should reap the benefits of the financial success of the school, which he's directly responsible for
What am I not comprehending?
If anything it's a terrible example to try to validate your point. Opening the pandora's box of paying a high profile athlete is a very convoluted issue. Who decides what players are "high profile"? Who decides the pay scale? Are we talking endorsements or a set salary? Since they are getting paid for their services, is the scholarship still a part of their package or are they ineligible for scholarships?
Refer to tmay's post, can some of it be attributed to the success of the football program? Yes, it's undeniable. It also helps that their is an Oil & Gas boom near the University, and that the University is growing/expanding.
