Rest the starters?
 

Your team is going to the play-offs, do you sit your starters or do you play them as if it were a regular season game? There are two school of thought, (1) don`t take a chance of injury. (2) Play them and keep them sharp and game ready for the play-offs.

My opinion is you play them. Your chance of losing a player to injury is the same risk you take at the beginning of the season till the end of the season. Play your best and hope for the best and hope you have a good medical staff if disaster strikes.
