That's a valid point. I do look forward to the QB battle next year... and Blaine will definitely be in the running this time. He looked solid Saturday night. There is a big difference in coming in late with nothing to lose versus having to own the entire 60 minutes... but I think he will be ready this next season. We shall see.
I too cannot wait to see what Rob Walker has to offer.
But, like you said, if we don't get better on defense, we are still going to be battling for .500 no matter what the offense does. We also have to get better special teams play. The special teams letdown on Saturday surprised me the most (despite having been poor most of the season). Our defense could not contain Jernigan/Brown and that did not surprise me. But, we had massive unforced errors on special teams... in the 12th game of the season. That was hard to excuse.
