Unrestricted FA Josh Harrellson is working out for the Heat on Thursday, a source tells ESPN's Tom Haberstroh. Miami is still looking for some depth in the size department and it's pretty interesting that they're working out Harrellson and have yet to make a serious inquiry about Andray Blatche's availability. Regardless, Harrellson would fit well with the Heat, a team that could use a big man who can hit the 3-point shot and stretch the floor. Harrellson made 33.9 percent of 3-pointers during his rookie season last year.
