Number 1 priority for improving defense is forcing teams to throw more and run less. Three things can make that happen: Improving the DL with stonger DT and getting a good strong safety. It wasn’t the same last year with Maye gone and hasnt been the same since CGJ left.
Next, if offense can build early lead then the opponent will be forced to pass more to catch up.
Its not complicated and its not rocket science. The Saints can be back in the playoffs in 2025 with these simple improvements.
