Here is a piece of selection trivia to start things off.  There has not been a double-digit seeded at-large team with a non-conference strength of schedule ranking below 240 since 2006.  The at-large teams seeded 10 and below typically represent the last 8-10 teams selected.

Current bubble teams with a NC SOS ranked below that are: Penn State (254), Michigan (255), Nebraska (261), Houston (262), NC State (271), Florida State (287), Mississippi State (303), Virginia Tech (325), Kansas State (329) — several of whom are in action Wednesday. It is a busy night throughout the bubble as teams like Michigan and Florida hope to play themselves to safety, while others like Kansas State and NC State hope to stay in the bracket for another day. 

CBS Sports’ Bracketology page breaks down all the numbers and key factors of the bubble, but there are still many games to be played. Here’s a look at the teams with the most on the line Wednesday night as we enter the home stretch leading to Selection Sunday (all times Eastern):
