Maybe. But there was nothing to stop us from signing Funderburke (or anyone else, for that matter) at minimum for a couple of years, exposing them, and waiving them if they weren't taken. Something like that would have been done if (a) Wallace's potential was appreciated, and (b) the management/owners weren't hell-bent on cost cutting. $800K and you'd save your player. I think they just didn't believe in Wallace, or he would have gotten way more play time than he did.
Gerald Wallace's work ethic was questionable during his time with the Kings. He needed to grow up ... and in Charlotte he has. He had raw potential here, but just didn't seem to want to put forth the effort necessary to become a solid player on a contending team.
