My wife and I had this exact conversation last night. There's little doubt that some of these kids will blow through this money and be worse off in the end, but that exact thing happens to 50 & 60 year old "mature adults" who win the lottery.
And you can't fault the kids for taking the money. It's hard to make a reasonable argument against Tyrese doing what he's doing. (Understanding he doesn't have parents...sadly) I told her that if she were in a similar situation in college, her mom for sure would have sat her down and told her to take the money. If you're in a situation where you are going to (as far as you can tell) receive a similar or better opportunity to play with a similar or better programs...but you are going to make 10s or 100s of thousands of dollars more. Why wouldn't you go? You're setting yourself up for the NBA just as well as you would be at ISU, but if you have a career-ending injury, you've already given yourself a financial springboard most don't have.
As fans we want the player to be committing to the coach, to the fanbase, to the name on the jersey more than to themselves. Things have changed though. The ESPNs and Fox Sports Networks of the world have taken advantage of our hobby/passion and created a multi-billion dollar behemoth that has kids hearing cash registers instead of "and the crowd goes wild" when they think of hitting that buzzer beater. If we keep paying, it keeps going down that path. It's kind of on us at this point (whether we like it or not). We didn't ask for it...we were just fans. But we do have to decide how we're going to continue to fund this thing.
