Literally NONE of those things pertained to Clingan.
He was always heavily favored to 'stay home', so that meant UConn.
By default.
He is very close to his family, and IIRC there also may have been some sort of family member health issue at play too?
Anyway - he was always UConn's to lose, and they didn't, by virtue of being right in his backyard.
Conversely - some kids just want to get the heck outta Dodge, and do so -
Like JJ Starling, for example.
His family wanted him to play at home, but he had other ideas.
