I honestly think Nevada and Gonzaga are legitimate top 5 teams. Never seen two mid-majors in the same season stacked like this before. Both teams could be 1 seeds.
Between the teams listed, I would go with Kansas. They have experience and depth. And probably the best frontcourt in the nation.
Texas should have beat Nevada last year. I don't think they are as good as you do. Top 25 yes.
OP should have included 'the field' as an option. I would have voted that way
Of the theth options given, all three will be very talented so I'll go with the best coach.
