Lakers coach Phil Jackson said, "I'm not so sure Dallas didn't outplay us."
So.... did the Mavs outplay them or not? I don't know! I don't even know what he thinks!
Just a reminder that double-negatives ("not/didn't") are generally confusing. Use them if you want a certain ambiguity or resonance (as with Iago's self-definition: "I am nothing if not contrary"). But don't confuse if you don't mean to confuse!
(I'm sure poor Coach Jackson was so perplexed at his #1 team yet again losing the first game at home in a playoff series that he just couldn't get a straight thought out. Plus he's Buddhist, right? So he's been schooled in presenting contradictions as wisdom. :)
