I don't think Ron favors rookies, I think he makes up his mind about the depth chart before the preseason even starts and nothing will change it except for injury. He's more willing to lose games than he is to change his mind.
He got what done? He was 7/13 with 2 interceptions and 59 QB rating. Cam performed WAY better than Brady. Also his weapons are all coming back. Edleman and LaFell will both play this season. They also went out to try to fill their holes with Wayne while we sat around figuring Brown would be enough. It's a totally different situation.
