That's because many people here play fantasy leagues or whatever and don't watch the teams play.
Tyreke has been a huge factor for them for 2 years now -- it was him going bonkers that first helped Davis emerge at the end of 13-14. last year he was a +4.8 as the steady backcourt guy that made their playoff run go. This year he is a +12.0, which is near superstar level impact, as the guy who rescued their season. Davis himself is only a +9.1
So yes, I am sure there are the same idiots in New Orelans' fanbase you find in every fanbase, but just having some dumb fans doesn't trump the statistically trackable impact Reke has been having for several years now.
He's not a SF, and he's not a bench guy. When he's got the ball in his hands, Davis gets better, and so do the Pelicans.
