Haven't heard the details of Wandale's deal but it has been reported that it is in the 6 figures.
Rutgers has 12 players on NFL rosters / Kentucky has 16 players on NFL Rosters.
I would guess that UK puts another 5-6 (at least) into the league after this next draft.
End of the day, you can never be mad at an 18 year old kid for making a decision that's going to better his life. Some players handle the decisions better than others and there is nothing I've read about Wimsatt to suggest he burned bridges or handled things in an unprofessional manner. I don't like the unsubstantiated rumors, mostly from Rutgers and UL media personalities, that Wimsatt had to "flee from Kentucky because of all the negativity after the commitment". I think that's all BS, people wanted him here but I don't recall seeing this outcry or backlash against the kid.
Best of luck to the kid and I hope he does great
