How good was Carr in his first start as a Saint?

I know it's not Carr's fault, but the red zone offense needs to work on some good routes and plays. We choked a lot there, seeming due to poor design.
I'd like them to play more of our big pass-catchers on the field in the red zone. That our red-zone trips really didn't get inside the ten, is probably the reason that we didn't see some of those three tight end sets I look for as the season progresses. Getting Kamara back will help too.
