In a move to help teams make cap space the extension deadline has been changed to:
February 14th, 2011 @ 12:00am to February 28th, 2011 @ 3:00pm
After the extension deadline any teams still over cap will not accumulate points until they return under cap. Also all teams must sign their respective prospective free agents in this time. If players are unsigned during this period, at season's end they will be released to free agency.
Another way to conserve roster space is to send a player to your minors but then the player will have to go through waivers and run a possibility of being claimed by another team.
