I remember a playoff game last year where the Spurs were taking an absolute bludgeoning at the hands of the Thunder in the second half; Pop pulled Parker, Duncan, Ginobili, and Leonard, while the likes of Aaron Baynes, Jeff Ayres, Patty Mills, and Marco Belinelli led the Spurs on a furious come back just to fall short in the end.
Even though, the Spurs lost, it was a great performance by their second unit. I always felt that game was a big factor in giving San Antonio a spark to get past the Thunder in that series.
