Playing rookie QBs can be tough. There's no game tape to look at. The offense usually has a number of new wrinkles as well. I remember the Saints going to AZ a couple years ago and losing to Max freakin' Hall in his first start. It happens.
Especially when the other team's defense scores 2 TDs and forces 4 turnovers.
I still love that game as yet another example of the wacky stuff the Arizona Cardinals do. They scored 30 points and not one offensive skill player scored a TD.
Defense and Special Teams scored 12 times that season. And they still finished 5-11.
You gotta love Cardinal football.
