Regular season does matter. But when you get a 1 seed you have expectations to live up to as well. KU made the elite 8 and was last 1 seed in the field. Grats.
But your bracket was an unwrapped Xmas present. There have been a handful of 1 seeds that have had easy routes to the final 4...... just almost all of them ending up getting to the final 4. 2 others off hand that were ridiculously easy were
1) Mich st got to play a 16,9,12,11 in 2001.... and made FF
2)UNLV got to play a 16,8, 12,11 in 1990 .... and made FF
No one was laughing histaricly when 1 seed KU lost to 2 seed Ucla a few years ago. Those 2 teams were very equal and the Bruins D was the big difference on why they were better than Ku
1 losing to an 11
1 losing to a 9
4 losing to an 13
3 losing to a 14
Sorry, but that should be unexceptable for a top 5 program. 4 times in 8 years under BS
Add in the 3 times in a 7 yr span where Ku failed to get beyond the sweet 16 as a 1 seed.... and its clear to see that no team underachieves more (to what their seed is) than KU
