What Ever Happen To Defense?

Apparently the Sixers forgot to play some last night in Phoenix. They fell to the Suns 126-116. And to add onto that, they were up at halftime, but Shaq took over.

If there is anything positive to take from this game, it is Thaddeus Young had another stellar scoring performance and Donyell Marshall had another productive game off the bench. He scored 12 points in 20 minutes and had a plus/minus of +12, the highest on the Sixers for the game.

It is obvious since Marshall is clearly the only 76er, other than Kareem Rush who gets as much floor time at the Sixers Dancers, who has a letal jump shot that he should get more minute.

Also, someone explain to me why Marreese Speights only played 4 minutes in the game and 5 minutes the night before against the Lakers? When he is in the game he is a high energy player and he is productive. 

I just don't understand.
