A few interesting non-Celtics free agency rumors that may have slipped through the cracks:

Kenyon Martin deciding which contender to join - Yahoo Sports

Kenyon Martin is expected to decide by this weekend which NBA team he’ll join, league sources told Yahoo! Sports. The Los Angeles Lakers, Los Angeles Clippers, Miami Heat, San Antonio Spurs, Atlanta Hawks and New York Knicks have expressed interest in signing the veteran forward.

The same article brings up the name of a former Celtic who is contemplating a comeback:

If the Lakers don’t sign Martin, they could have interest in adding Rasheed Wallace, who contacted the team several weeks ago, a league source said. Wallace retired after the 2009-10 season, but has told friends he’s interested in returning to the NBA.

Lakers ask about Gilbert Arenas - ESPN.com

Short on scoring and in need of help in their backcourt, Los Angeles Lakers coach Mike Brown said Tuesday the team has inquired about free-agent guard Gilbert Arenas.

"We've made a call on (him), yes," Brown said. "We've called to see what his status is. That's it."

Lastly, the Heat and Bulls are talking with another guy that the Celtics have reportedly expressed interest in in the past:

Przybilla is expected to make a choice between the Chicago Bulls and Heat, according to agent Bill Duffy.

So, what do you think? Kmart, Joel P., Sheed, and Arenas: are we missing out, or are these guys who won't contribute much anyway? And should we read anything into the fact that the Celtics aren't involved in any of these talks?
