 A number of teams essentially know that they are assured of an at-large berth no matter their performance in their conference tournament.Most teams in the Top 25 in the national polls or RPI are essentially guaranteed at-large berths even if they do not win their respective conference tournaments.However, teams that have been ranked heading into Selection Sunday but didn't win a weaker conference's tournament have been essentially penalized (or "snubbed") by the selection committee despite computer rankings or public opinion.
