I wouldn't drop Gonzalez for any of these players...
He's been great this year and better than those other 3 players on the year so far. GB pass defense has been pretty bad although I don't know how effective they are against the TE, but regardless with White and Jones in the lineup Tony G should be able to find plenty of holes. The Falcons pass a lot and I don't see any indication that they're going to try and run the ball more especially if they're behind, which is probably going to happen pretty early against GB.
If you hate Gonzalez for w/e reason you may have, I guess I would go with Pettigrew. Played well so far and has a lot of upside in that offense
