Help with IDPs

Thanks to you, I nearly made it to the playoffs last year - wish I'd found you sooner!  Anyway, we start 1 DL and 2 any D.  I've got Pierre-Paul at DL with TJ Ward & Posluszny.  Weatherspoon, Lee, Y Bell & Harper are available.  Scoring is 1 pt for passes defensed and assisted tackles, 2 pts for tackles, 3 pts for sack, FR, INT and FF.  Should I get rid of Ward or Posluszny to pick up any of them?
Thanks

Drop Ward and pick up Lee.

Thanks for the prompt response!

Dude - AWESOME call on Sean Lee!  18 points already and there's still 10 minutes to go in the game. Thanks
