These statements are not accurate. The NCAA men's basketball tournament is currently very popular and highly significant in the world of college basketball. It typically draws large viewership and is highly competitive. The NIT tournament is also considered prestigious but is not as popular or widely followed as the NCAA tournament. Teams compete in the NCAA tournament based on their performance during the regular season and conference tournaments, not due to their inability to compete in the NIT.
