Was he caught tampering with a player from another team?
This is what was told to me. A player from another SEC school transferred here with assurances of a certain amount of NIL money. Perhaps because the player didn't perform up to expectations, and indeed didn't play much, the money wasn't forthcoming to the extent the player thought was promised.
The player's girlfriend approached Edwards with texts on the player's phone between Edwards and the player concerning the money and Edwards' early contact with the player (the player was first contacted before he was ever in the portal). In an attempt to secure the money, payment was demanded by the girlfriend, who threatened to expose the matter if the money wasn't proffered.
From there, this affair became known (either from Edwards or the girlfriend) to the athletic department. The result was the separation of Edwards from the university.
