That small ball lineup at the end of the half with Richard Jefferson at the power forward spot against Luol Deng. That's a terrible matchup for San Antonio. Deng can tear RJ apart, particularly on the offensive + defensive glass with his rebounding.
That's a really poor small ball option for the Spurs ... I don't think this year's Spurs can matchup with those combo-forward types. Couldn't last year either.
The Spurs have something against wing players who rebound. They have only one decent wing rebounder on their roster -- Ginobili and he's excellent, and it's one (rebounding) of the (many) reasons why San Antonio always plays so much better when he's on the floor. Because their bigs are finally getting some help on the glass.
