I'll go with Patterson as the top coach, but because it's an ISU site, they're almost certainly going to list Campbell because he's had 2 really good seasons. Riley should be there too because he's never actually not won the title.
As for hot seat, I think that's by definition the UT coach (Sark) because they tend to fire anyone after 3-4 years. But because he's just starting, they'll probably put him the rising stars camp, so Welch (Tech) and whoever is at KU will probably be their choice.
My rising star candidate would be Campbell but this site is going to list him as best already, so they'll probably go with Sark and the Eer coach.
