If memory serves me correctly, back when Dikembe Mutombo was a free agent a couple of years ago, it was noted that he prefered to stay away from cold weather cities, and thus why he favored Houston. But now that he's hoping to play again in the NBA (and Houston has yet to return his call), he may have to broaden his geographic preference. And if he wants to wear a championship ring on his finger, he may want to shop for thermal underwear and sign on with us.
Even though he's no longer the league's most feared shot blocker like he was in his heyday, he's still a defensive presence, due to his 7 foot frame, long limbs, and timing. He's never relied on jumping ability to be a shot blocking force--it was always about positioning (both his feet and hands) and excellent timing--so that's why at 43 years old, he's still being sought after by a handful of teams.
I certainly don't mind bringing PJ Brown back for his second call of duty, but I hear he's 50/50 on that. If Mt Mutombo can deal with cold weather for a few months, he'll provide solid backup minutes behind Perk.
