McCarthy

He's concussed and has been average at best this year.  Is it time to let him go??  I picked up Zach Brown this week.  My current LBs are Brown, Kuelchy, Derrick Johnson, and Burfict.  Ray Lewis is available, and I could drop McCarthy to pick Lewis up for my playoff weeks when he plays against DEN and NYG....thoughts??  Thanks Guru!!

There's no guarantee Lewis returns Week 15. Otherwise, I'd say let McCarthy go. But he's likely to have at least one big game before the year is out.
