Can you name any players that the Saints wanted to sign or keep, but couldn't because of how they manage the cap?
I can't think of any players. If the Saints are able to sign and keep the players they want, then the way they manage the cap is not a problem.
The Saints haven't had a cap management problem the last few seasons. The problem the Saints have had is that Allen made bad decisions regarding who to get and keep, how to use players, how to coach and develop players, and how to keep players healthy.
If Moore does a better job in anyone of those areas, the team will get better even with the same cap management.
