If you're so passionate about playing Hayward at SF - then let us hear a proper argument from you instead of starting off calling someone an idot and not backing up your claim.
I do not care if Hayward plays SF or SG. He is a versatile player who should be treated as such. Too say he is only a SG, or only a SF, would be incredibly stupid. We should get the best possible player, whether that player is a 6'4 SG or a 6'8 SF shouldn't matter.
