"Good for the game" is ridiculous. NIL is awful for the game of college football. It may be good for the players who get paid, but it is poison for the sport and poison for the landscape around it.
If people can't see the difference between being supporters of a group of college students who choose to play football for your school, and supporters of paid employees who play football for their job, I don't know what else can be said. It's an entirely different spirit. In the latter, which is what some people have pushed, no, demanded college football become, you don't get the luxury of support.
Let's say we get to a world where the big schools are paying people left and right - through their legal third parties of course. If you're a sophomore quarterback who is struggling, you're dead meat. And you should be. It's not a "school spirit" thing anymore, it's just your job, and if you're bad at your job, you get fired. Or say you're a wide receiver who is having trouble adjusting to the scheme. Same result though, your ass is canned. College football isn't going to be about watching young men come together as teams and grow over the years to achieve success both personally and as programs. It's just going to be results, and only results (which it's been trending toward for years now thanks to the BCS/CFP), and anything else? Waste of time. If you can't hack it, you're gonna get cut.
Then you add the portal in, and people shopping themselves around at the drop of a hat, and there won't be anything much left to invest in. Why care who's on your roster? They may be gone in a year. Or they may only be there for a year to begin with. Lotta senior paydays for people with talent. Same difference. Just people coming and going. Is a guy who plays three years at Local College Tech and then one mercenary year at Bigtime State really a "Bigtime State" player for life? Imagine teams where half the players are one year rentals from the transfer portal, guys who you don't know and who won't be around long enough to get to know. Is that what school pride in college sports looks like? I can't see myself caring about that at all.
Anyway. NIL is just fuel on the fire, and the fire was built on a foundation of TV advertising money that has slowly roasted college football alive.
