No. No, he wasn't. Pickles was the emergency 3rd QB. Per NFL rules you can have one QB that's "inactive" in regards to your "active" game day roster, who can come in as an emergency injury replacement.
Pickles was our 3rd QB all season. AE would have been fourth, if such a thing even existed.
That rule change a couple years ago. How do you figure Jimmy was going to enter a game when he was wearing a TShirt and gym shorts?
