It without a doubt needs to be increased, but the problem is the players really don't want it to happen, especially if they aren't getting paid while the colleges rack in millions. There has been way too many injuries in bowl games that have cost or nearly cost players career. Marcus Lattimore was considered to be a generational RB, college injuries ruined his career. Jaylon Smith suffered a horrific leg injury vs Ohio State a few years ago and went from top 10 pick to 2nd round pick, and just this year finally has gotten back to where he nearly was.
Even this year, Nick Bosa, projected top 5 pick, was hurt early in the season, he told OSU he wasn't going to play the rest of the season to preserve himself for the NFL. Star Corner for LSU Greedy Williams is considering sitting out the bowl game as well, he just declared for the draft.
