I come to this number pretty easily. Other sports leagues - the NBA, the NFL, the NHL - all have their players form a union. As part of this union, the players negotiate a share of the revenue.
Using the NBA as an example, the players get 50% of the revenue and the owners get 50% of the revenue. Revenue is considered ALL money made, this includes TV rights, ticket sales, licensing agreements for jerseys, concessions at stadiums, parking, etc. Now, under the salary cap structure of the NBA/NFL not each player is paid the same amount. But you get the idea.
For a player at the University of Nebraska, the amount of revenue generated per year is approximately $110 million today. It's hard to say the exact amount, but consider $70 million in tier 1 TV money (the new deal just signed by the B1G). There's also tier 2 TV money via the Big Ten Network. There's bowl money, college football playoff money, Adidas money, ticket sales, concessions at the stadium, etc. All of this adds up and I conservatively guesstimate that the amount is probably around $110 million. In reality, it's probably higher than that.
Once you get to the revenue number generated, the CFB Players Union will likely negotiate a 50/50 split. That leaves $55 million for the school, and $55 million for the players. If each team has 85 scholarship players, divide $55 million by 85 = $647,000 per player, per year. This of course assumes a fixed rate per player (QBs make the same as the second sting punter) but you get the idea.
My opinion on the money they make is simple: if the market determines that the players generate this much money, then they are entitled to it. No different than you are with your company or I am with mine.
