I think it started with fans from other teams trying to describe him as a player and doing so incorrectly, while Bulls fans are labeling him as a great player and correctly? I can't remember.
Well, whenever Derrick goes nuts they say "Derrick going into unicorn mode" or something like that. Or during the cavs game when he had that amazing third quarter someone said something along the lines of "unicorn mode and it's not even the fourth quarter yet"
Rose has been a frickin monster this year though. Every time I see the guy take over, he makes me feel like a dumbass for wanting Beasley over him on draft day.
You shouldn't beat yourself up over your prefered player during that draft; no one could have known how great Derrick would be (and so quickly too) and there was never any reason to believe Beasley would be this...blah.
