Triplett: Spencer Rattler has started ‘rolling’ in Saints camp, but preseason looms as ultimate test

I am really excited to have a young QB that can make off schedule throws. That, along with red zone performance, IMO is what separates solid NFL QBs from good/great NFL QBs. Almost all of the QBs in the NFL can pick a D apart if they have time to sit in the pocket. The key is what can you do what things break down. And Rattler has the arm to make some throws that even Carr, who has a good arm, can't make.

As far as who is #2, I don't think it really matters much at this point. Carr is starting unless or until he gets hurt. If that happens, I could see some sense in putting in Haener to allow Rattler the full year to get ready without getting killed as a rookie. Then again, if Rattler shows to know the offense better, then maybe he ends up the guy to step in for Carr.
I think the #2 QB position is subject to change even during the season.
