Hornets are 5-5 because they're not that good.
It's literally Cp3 and a bunch of scrubs. Sure West is "good", but I could name 7-8 power forwards better than him (Garnett, Brand, Bosh, Gasol, Duncan, Nowitzki, Stoudamire, Boozer, Jefferson etc). Then the 3rd option Peja disappears in teh playoffs and apparently is cooling off from a flukishly hot 3-PT shooting year last year. Then Morris Peterson is a terrible shooting guard. Then Tyson Chandler has no post game and si a mediocre defender.
And then there's that bench. Sad thing is they're 5-5 despite Posey shooting a ridiculously high 3-PT % which is bound to cool off.
