Saints Cap Moves: $33,780,933 cap space ….. 8 restructures, 3 extensions, 3 pay cut, 1 release [All current cap moves are in OP below line]

Accurate, Kellens entire Career has involved him getting production out of young QBs.
Moore moving on from Carr probably indicates that he knows he can get equivalent production with a different QB. He likely wouldn’t be relying on Rattler in his first year as HC. Wilson, Rodgers, Ward, Sanders, or Dart would be lateral, at bare minimum, to Carr right now.

He could probably get a couple more wins with Wilson or Rodgers. Sanders, Ward (obviously takes a monumental trade), Dart (maybe not at #9) would be current-Carr impact as rookies imo.
