Matt Schaub is a RFA. I would target him and then release Joey.
Atlanta won't let go of Schaub. Especially not with Petrino as their HC. Not a snowball's chance in hell. And with Lemon outplaying Joey in the final two games of the year (and Cameron apparently having a high opinion of Cleo), Harrington's gone anyway. I see them release Joey in the near future, go after a development QB in die draft and have Lemon and Culpepper battle it out in camp.
