Sixteen teams are left standing after the mayhem that ensued last week. Some, such as Texas A&M, were fortunate to get some last-second luck while others, like Villanova, just flat-out dominated the first two rounds.
Now it's time to look at how they got there, and what they need to do in order to get through the next two games to wind up in Houston.
What they did right: The Jayhawks were terrific defensively against UConn after being lackluster on that end of the court in the rout against Austin Peay.
What they did wrong: Coach Bill Self's team is one of the deepest in the country, but he only played his bench a total of 29 minutes in the win against UConn.
What they need to do to survive: Play defense. The Jayhawks have plenty of guys who can score, but if they guard at a high level, they will likely have a trip to Houston in their future.
