Reset is not possible
Bringing back aging veterans like Mathieu next year is going to be brutal to watch. His lack of effort this past Monday was putrid. Some of the other aging veterans still give it their best shot but father time has caught up with them.
To the OP. A reset is not possible because of the Loomis Model. The Saints are currently one of the worst teams in possibly the worst division in the NFL. I also can't place most of the blame for the decline this year on injuries. The Lions have been decimated with injuries to key players yet they're still one of the best teams out there. The Saints just don't have the players from most of the starters to the backups. The draft is our best hope to get back on track.
