I think he may be a player a general manager might want more than a coach. My feeling is that one key trait GM's look for in players is that they can score consistently. Bradley can score. Obviously coaches want that too. But they are at the floor level and may be better judges as to players who elevate the team's play as well. Bradley doesn't really do that so much.
He's a bit of an enigma for there are parts of his game we love and others not so much. I believe he'll get his $7-8.5 million/year. $6m is on the very low side. He's turned into a very dependable shooter and they've been known to get $10 million a year or more without any defensive prowess.
