I think its more grant williams. If you keep Grant you cant use the MLE. so if you sign Beverly to any part of the MLE that means Grant williams is 100% leaving.
clearly they haven't made up their decision on him.
I think they want to find a way to convert Brogdon's salary into a cheaper backup PG and cap space/money for either Grant or a reasonable facsimile. However, teams with cap space that don't have to give salary back might need to be involved in the Lillard and Harden deals right now.
My reading is they would still keep Grant at a reasonable figure (full mid level) but are also open to S&T if he gets too expensive and they get something back. Then they could use that asset or other ones to figure out the Brogdon thing/and/or get Grant's replacement.
Whatever way or order it happens, I think they want to end up with Brogdon out, a cheaper backup PG in, and either Grant or his replacement with the remaining chunk of the money. I don't really think it's about not having made up their minds on Grant's value.
