Maybe. But maybe Moore and the FO want to win, and Carr gives them the best chance of doing that. I'm good either way, but I wouldn't be surprised if Carr is the starting QB next season.
I wouldn't be surprised if Carr started next year either and I think he likely will, but there are reports that the Saints told Moore they would be patient with him as HC and let him build the team he wants over time. So, there may not be pressure to win next year. Given Carr's age he's not likely to be here past 2 years if not past 1 more year. Given that, Moore may want to move on this year and find out what Rattler has to see if he needs to draft a QB in the next draft. That is assuming they don't take a QB in the draft this year.
