I'm totally against it too. Barry and Devin are both more valuable to the Spurs than Finley could ever be. MB makes a good point on Barry's value. Devin, of course, is an all-around fine player with tremendous upside.
If anyone thinks Finley is gonna "bear down" and start playing defense, consider this. Avery emphasizes defense as much as Pop. He basically executes the same defensive schemes as Pop. Last season, Finley drove Avery nuts for two reasons: First, he doesn't play defense. Nelson never stressed it, never required it and now it's part of who Finley is, as a player.
Secondly, he was and is simply a stand-still jump shooter who rarely goes to the rack. Translation: he rarely gets rebounds or gets to the FT line. Furthermore because he's a catch a shoot guy, the ball doesn't move around the perimeter after he gets his hands on it. This point was reinforced with the absence of Nash. I've watched this guy clang missed shots in the playoffs the past 3 seasons. Anyone remember his 1-17 performance against the Spurs in the 2002 playoffs?
Still want Finley on the team? I don't.
