I'm squarely on the fence.
I'm a big Russell fan, but I'm starting to think a different direction may be necessary. Not because of today; even NFL franchise quarterbacks have an occasional game like this. But like so many have said, Mullen just doesn't seem to be able to use Russell effectively in an offense he's comfortable with. Unless Dak blows him away in the offseason, I'd like Russell to start the season and see if he gets a little sharper with what will probably turn out to be a better receiving corps. However, if he or the offense struggles, a full switch to Dak should get some serious consideration.
