Preseason rankings are difficult and obviously nobody can see a future. With the portal explosion it makes things even more difficult to evaluate.
My guess is Kenpom didn't deviate too far from other preseason polls that were submitted last year.
With that said, here's a small sample of preseason polling from last year
AP Poll -
UNC #1 - did not make NCAAT, these guys were a consensus #1 probably everywhere.
UCONN - Unranked, Won the title
Miami - Unranked F4
FAU - Unranked F4
SDSU - #19 - F4
With that said, I'm sure the polling did accurately identify some other teams, sure. But they also probably had a handful of teams miss the NCAAT that were in their T25s in addition to UNC.
The ACC is down from a reputation standpoint with UofL and Syracuse slumming now but were previously cornerstone programs for decades. The league got shamed by pundits the last couple years but still held their own in the NCAATs. My guess is something like that could happen again.
Then again maybe not. It seems unlikely our Cards are going to be doing much, or anything in March.
