Drop Sean Lee or hold for playoffs?

Im set with Bowman and David, but Sean Lee is basically the IDP MVP of 2013

Still, i could use the roster spot.  Is he a must hold?  or drop and risk losing him to another?

It's depends on how long your playoffs go, but he's probably going to be out until Week 14 is my guess.

I think he's a must hold.  But then you need to make it into and through the first week in the playoffs to use him.  Depends on how solid your team is and if you are stalking up for a playoff run or in desperate need of wins to get there.
