Yup, absolutely every card that is not the regular gold, silver or bronze seems to have those attributes flipped.
Diamond KD, Sapphire Wall, George, Curry, Westbrook, Lillard (he has a terrible post fade so its not a big deal on him) have it flipped.
Archibald has 66 hook, 40 fade, which from a gaurd means its probably flipped.
Onyx D Will has it flipped at 77 hook 42 fade, Ray Allen has 77 hook, 40 fade.
Onyx D Wade Has it flipped also but its noticeably less degrading to him since he has always had a solid hook shot for a guard (78 hook 72 fade)
The ones you dont notice it on are Amar'e and Elton Brand who have either the same or 2 point differential in both.
However, for most guards(D Wade slightly not being handicapped by this), and Dirk + all future Onyx and Gem players, this is a huge flaw that devalues them greatly.
2k Should seriously consider taking a look at this issue.
