How?
By missing his shots and being a tired ole bag. Sorry ass number 1 option.
What's funny is that Pop had it all figured out. He thought all Timmy needed was some rest so that he'd be fresh going down the stretch...I can only imagine the thought in his head when he realized that Duncan was really as bad as LA fan advertised.
He was prolly like...Ohh this cat really can't play no more...

....he tried to make us all think all was well in Spur land and even gave him a bogus All-Star nod....however, Z-Bo and Mr. Marc was on a mission to prove he had no business at that All-star game...

@ your number 1 option.
