I thought 91 UNLV and Duke 99 were better. But those are the 3 greatest non-winners of my lifetime I think (also UNC 84...so modern era). But Duke and UNLV did win titles with those players. Just not in those specific seasons. I would also say all 3 are better than 2015 UK which was undefeated going into the Final 4. In my lifetime Michigan probably had the greatest 2 or 3 year run without winning the title
