Avery Johnson's tenure as Nets coach may be nearing an end, writes Chris Sheridan. Sheridan writes...

Here is how one NBA executive described Avery Johnson’s job security this morning: "The watch is on."

As in death watch.

"A flammable situation," was how one Nets player, speaking on condition of anonymity, described it to SheridanHoops.com. "Jerry Sloan all over again."

Sheridan adds that " it wouldn’t surprise me if he is out of a job before tipoff Friday night, with his replacement having a winnable game against the Bobcats to get the team back over .500 after its demoralizing loss in Milwaukee last night."
