According to Wikipedia, NFL agents get up to 3% of their client's salary. The NFL caps that commission to 3%. They also get upwards of 20% of player endorsements.
By some accounts, Tunsil could be the #1 pick in the draft. 3% of the 2015 #1 picks's salary would be about $700k. So Tunsil's agent easily stands to make $500,000 to $700,000. And that's just Tunsil's first contract. If Tunsil stays with the agent, he gets more than that in contract 2 after about 4 years. OL don't get much in endorsements, so I'll neglect that.
Ol Flab here has been asing questions for a week, collecting facts, and considering many scenarios. Here is what I think is likely happening in the Tunsil story. This is just my leading hypothesis. I am making no accusations. I'm taking a guess at what has happened to now and what will happen in the future. The following is completely fictious..unless it becomes true.
Lots of agents are trying to win Tunsil. Its crootin season all over again.
Stepdad was offered a commision to win Tunsil's signature. Probably six figures. Let's call it $100k. Stepdad has 100,000 reasons to get Tunsil to sign with "the right agent".
Stepdad and Tunsil argued over agents. Tunsil found out, probably from another agent, that Stepdad's influence had been bought. They get in a fight. Tunsil beats the crap out of Stepdad.
Stepdad sees his $100,000 evaporating and is absolutely livid. Stepdad seeks to burn Tunsil as much as possible.
Tunsil's draft status is already locked up. He's going to go where he's going to go no matter if he plays this year or not.
So Stepdad can't do any real damage to Tunsil, but he's going to make as much noise as possible. He's going to expose everything he knows in regards to Tunsil and the Ole Miss crootin machine. He probably doesn't know dirt on other players. But he's going to make Tunsil sit out of football this season.
Tunsil is declared ineligible and never plays another down of college football. Nothing else happens to Ole Miss. No probabtion, nothing.
Ole Miss finished the regular season 7-5 and has a top 10 recruiting class in 2016.
