If you have a JR or a SR that is a real Turd, don't be afraid to bench him, I've done it. Even though a FR or a SO may have a lower overall rating, but way higher potential, you'll do yourself a world of good by getting the younger guy in for some real playtime/experience now. You may get the snot slapped out of you this season, but next season you be worlds ahead with the young guy getting experience.
