We can’t play a BIG team until the Sweet 16 right?
Depends on how many times you played them. The bracketing principles state...
“Teams from the same conference shall not meet prior to the regional final if they played each other three or more times during the regular season and conference tournament.
Teams from the same conference shall not meet prior to the regional semifinals if they played each other twice during the regular season and conference tournament.
Teams from the same conference may play each other as early as the second round if they played no more than once during the regular season and conference tournament.
If possible, rematches of non-conference regular-season games should be avoided in the First Four and first round.
Any principle can be relaxed if two or more teams from the same conference are among the last four at-large seeded teams participating in the First Four.“
