Let's not overreact here. One good game in December of a rookie season probably means nothing.
I will now prove my point:

Well, thanks for the memory and the major laugh I got from watching this again. I almost with KK2 had stayed with us just so I could yell BOOM B!TCHES ever time he scores a basket. It was a blast in the playoffs last year, and every time I did it, my gf would just bust out laughing. Not because she got the joke, she just thought I was weird.
I even yelled it at Skybox during game six and everyone around me thought I was nuts.
Anyway. I don't think you should be comparing KK2 to Hayward. Hayward has MUCH more talent and potential. We all know that KK2 will never be that good. I don't think he has ever scored 17 points in a game either.
A more apt comparison to prove your point would be to bring up Gaines and his game against Cleveland last year.
