Original: In the second round, or Conference Semifinals, the top remaining conference seed plays against the lowest remaining seed, and the other two remaining conference teams pair off (unlike the NBA, for example, where the 1–8 winner always plays the 4–5 winner, regardless of who wins).
Simplified: In the second round, or Conference Semifinals, the top ten conferences that are still in the playoffs seed plays against the lowest remaining seed, and the other two conference teams play.
