QB trade help needed! WHIR

12 team PPR keeper league
Starting lineups include: 2QB 3 RB 4 WR 2 TE 1 WR/TE
He wants Housh and Bell, and is willing to give up McNabb, but I dont want to lose to much to get him...as you can see I'm hurting at QB.
I would like to get Johnson or Bowe, but who should I offer with Housh/Bell??
