I regularly play NCAA basketball brackets with questionable success

This year I want to back some outright winners outside the top 3 odds-favs!
Anyone got recommendations about some dark horses?
One team I will surely back are the defending champions Florida Gators - not sure if it's smart!?
Florida will definitely be a team to keep an eye on for this year's tournament.
As the #1 seed in the south, later tonight we will find out if they play either Lehigh or Prairie View.
Regardless which team it is, they should be 25+ point favorites and easily advance to Round 2.
Arizona is the favorite this year, at least most of the sports shows I watch favor them. Lot's prob think Duke as well, but I don't think Florida makes it past the Elite 8 round.
Wouldn't mind seeing something interesting from rainbet for the tourney but might be a little late unless it's only some little final 4 promo.
If I were to have my money on team blindly here right, I’ll likely have it on Houston, remembering what transpired last season and how they were in the position to win the title before losing to Florida, I think nothing serves as a better form of motivation, and maybe it would be better not being rated as the No. 1 seed, that could reduce the pressure on them.
I’ll also be looking forward to the outright odds to see if I could find some odds of decent value.
