Pop hasn't looked so hot. He was trying to ride Timmy with repeated post-ups as if it were 2007 instead of staying with the type of stuff they've run all season.
They do have serious matchup issues, though. Like Lawson in the first round, Parker is the offensive catalyst that can't defend either of the Warriors' starting guards.
More generally, San Antonio plays its "A"-game more consistently than anyone else in the league in the regular season. I have doubts about their ability to take their game to another gear in the playoffs. The Spurs' Big 3 isn't what it once was, and they're too dependent on role players that just aren't that special.
