There's that one guy on every college basketball team that the team cannot win without. He is the best, most important, most indispensable player, and everyone knows it.
Each team in the top 25 has one of those guys where without him the program would plummet in the rankings to the points where a top 10 team could fall out of the top 25.
Losing this special player would be devastating for the program, and a long-term injury would sink the team's season.
These are the guys whose teams cannot go on without.
