Throwing a zone out there isn't the only thing Pop does to mix things up. I liked your first post timvp, but this one needs some serious checking, my friend. Whether it is doubling the ball, trapping corners, doubling a hot scorer with a big, or sending doubles from different places to mix things up is what the Spurs do when they are at their best. Example, moving Bowen to defend Chauncey Billups at the end of game 5 and game 7 of the Finals is mixing it up, even if it is part of an overall game strategy.
