I still don't fully understand where Ignite is getting (or, more accurately, why they're spending) this money.
If this were like European football and they were signing some kind of juniors/development contract with an established team to play for their G League feeder until eligible, that would make more sense but be a glaring draft loophole; Ignite, to me, is just paying kids big money to bide their time until drafted without benefiting from the marketing or revenue bumps that a college program gets from fielding a competitive team.
