Michael Wilbon calls on the NCAA to "leave alone what works" as talk of expanding the tournament grows (1:23)Open Extended ReactionsDespite plenty of hand-wringing from college basketball purists, expanding the NCAA tournament isn't the terrible idea many have suggested. Instead, the NCAA looks likely to approve an expansion to 72 or 76 teams, possibly as soon as this week. Think back to the introduction of the First Four to the men's tournament in 2011 (the women's tournament would incorporate it in 2022). Instead of eight teams playing four opening-round games, a 76-team bracket requires 24 teams -- a massive increase -- playing 12 opening-round games. But a fractured sport without the NCAA tournament as we know it would be far worse.
