OBJ and Bowser are gone, I suspect. I personally can't see them paying Ricard $4M or carrying him at $5M either. I think he'll need a paycut, extension, or be cut entirely, to stay.
I do think one of either Stanley or Moses are cut, likely the latter. I can't really see a world where they cut Stanley before the draft, even with that much cap savings available.
Mekari is a FA after '24, so I think they'll extend him and look to lower his cap #. His base comp is incredibly reasonable for one of the games best swing tackles. Especially when he could easily end up the starter at RT to start the year.
