I have officially quit the whole Mavs vs Spurs smack talk stuff...it's late enough in the regular season so that both teams know how good their chances are, and there's no need to say "such and such is more young and athletic", the actual playing of the games will speak for itself, whether the old team or young team is doing well.
I've been guilty of smack talk, but...it's April, and the playoffs start in what..2 weeks?
And last time I checked, SA has won 18 of 20, and is currently playing .500 against Phoenix and Houston, with 1 game left vs Utah and Dallas each, going into those games playing the best ball they have all year. That all speaks for itself, to be doing this well after SA hasn't struggled this much since probably Duncan's injury in 1999-2000.
