Here's the bigger issue to me. When ESPN, as the holder of the rights to the tournament, goes all in on one person, or on a few teams, you have to expect the integrity of the games to be questioned. They have a massive financial outlay that doesn't cash in unless some combination of Iowa, LSU, UConn, South Carolina and Stanford makes it. They've completely hitched their wagon to CC and Iowa, and it's not hard to surmise how much money they are out if it winds up WVU/Colorado as opposed to getting to LSU/Iowa.
Was it "rigged"? Who knows. But I do know that when the entity that holds the broadcast rights very openly roots for a handful of teams, it's going to call into question the integrity of the games.
