Deadspin had a good breakdown of the salary structure. MLB is waiving rules so that they can market that they got the Heisman Trophy winner (not sure why people would care, but ok), that's where the extra $15M is coming from. But supposedly he doesn't get it until he gets to the majors. However, in baseball, arbitration rules don't let people get paid big dollars until they're 28-30 or so. And we've been starting to see how analytics and moneyball practices are beginning to eschew the huge free agent deals and squeezing the market.
So, if you're Kyler Murray, where's the money coming from and when are you getting it?
