I can't conceive of any way in which Ian would be considered for activation for any single playoff game UNLESS the Spurs suffer a rash of injuries [knocks on wood] and need another body to fill out the roster minimum. The guy has played one basketball game all season and has played 23 minutes of basketball at the NBA level and there's actually some thought that Gregg Popovich is going to make him an option for a playoff game?!?!?!
If Pop holds to form, there will be very little change from game-to-game or series-to-series and the Spurs will suit up the same 12 guys on just about every night. I think the end of this season becomes an audition for Malik Hairston to see if he's outplayed Ime Udoka and becomes one of the 12. I think if neither shines from here on out, Pop goes to his old favorite of having Vaughn active. The other 11 spots -- assuming Gooden comes and is healthy -- are all but set in concrete, barring injury.
