Jaden Mickey isn't in that category. He simply wants to be a starter, and will have his degree when he leaves.
He was a productive contributor, and could have been a starter if it weren't for the strong talent seizing those positions.
With regards to the UNLV QB, he's a mercenary. Mercenaries get paid, and if you don't pay them, then they'll simply walk.
Everyone should have learned from the painful lessons of the Jaden Rashada incident.
The Cliff's Notes:
One of Miami's biggest boosters, a billionaire, offered Rashda 9.5 million to commit to Miami. He accepted.
Billy Napier (U Florida) and some boosters at U. Florida told Rashada that they could pay him 13.5 million for his commit. Rashada flipped his commitment to Florida.
Napier and friends renege on getting Rashada that money. Rashada flips to Arizona State, where he gets brutalized behind that awful offensive line.
Rashada flips to Georgia, and is now suing Napier and friends.
