I don't know if there are unwritten rules about this stuff or not, but it's probably not a great idea to date a former teammate's ex-wife. Especially when that former teammate is Matt Barnes, whose ex-wife has been reportedly dating the former Los Angeles Lakers guard-turned-horrible-New York Knicks head coach for several months now. This was technically an off season story, but Indiana Pacers fans have resuscitated the story after chanting "Der-ek Fi-sher" to Barnes during his Memphis Grizzlies recent visit to Indianapolis.
