I think truthfully, the offense will not be as good as it appeared on Saturday night; nor will the defense be as bad.
Cam's not going to be able to run around and "make plays" against an SEC defense, so his accuracy with the deep ball will be of utmost importance from here on out. If he can get the ball to Adams, Carr, Reed and Zachary in stride every once in a while, the underneath routes will open up, as will his escape route lanes if the pocket collapses. If he struggles throwing it up top, the entire offense will struggle mightily against USCe, LSU and bammer especially.
On the other hand, as the young guys on D get more comfortable in the schemes, and Stephens gets back on the field, the D will probably actually be pretty good. No...they won't be a top 10, probably not even a top 20 unit overall. They will be steady against the run and decent against the pass. I have a feeling that Mallett is going for 400+ against this unit though. Hopefully most of that will be between the 20's.
