It’s sadly just due to the AVP offense which doesn’t really use the slot receiver much.
I’m sort of interested in the idea of bringing back McDaniels (under Vrabel) who obviously knows how to feature the slot receiver and got everything he could out of Welker and Edelman. Bourne also had a fairly solid season under him in ‘21 with only Jakobi Meyers across from him. Replace Meyers with Higgins and put Pop in the slot, and Maye throwing instead of Mac, and it would likely be decent. Bourne, Pop, Henry, Boutte, Stevenson all know the offense already so it would only need to be taught to a few guys. Also makes life easier on the OL. Probably hardest on Maye.
