If you HIRE him, they will come
Should Brown leave, is there any coach that we could hire that would attract a marquee free agent?
Keep in the back of your mind that the Bobcats have some players that they could trade to free up some space for a bigger signing, from Stephen Jackson all the way down to some of the big guys on the bench. At this point, I'd rather have Al Jefferson on the roster if they have to give up Jackson to get him, even though I'd rather get another two guard for Jackson.
Either way, is there a coach that might attract a James or Wade or Bosh, if the Bobcats freed up some space to get a player? Once you get the name, the revenue and investments would increase to pay salaries and make the team profitable.
