Baun not re-signing or not performing the same as he is in Philly isn’t close to a coaching issue. Baun started games and saw the field as a LB in base and heavy. There’s nothing the coaches could’ve done differently for Baun when they had 2-3 legitimate starting LBs throughout Baun’s time here.
The FO is who could’ve made sure they lock up Baun long term. But it was Baun’s decision to seek the opportunity for eventual bigger salary and increased starting job that he felt he deserved.
His season in Philly will likely lead to 10M+ AAV in his next deal. He’d be looking at a max of half of that if he stayed in N.O. behind Davis and Werner. A deal in N.O. could’ve been structured for him to get near double digit AAV in the year that Davis retired but doesn’t make sense for the player to wait 2 seasons for it.
