Would not trade Parker for Rondo. The Spurs have a good offense, but Tony Parker is a key piece in it. I'm not ready to dump a guy who's been a 10 year fixture on the team and helped bring 3 les to the town for a guy I've always felt is overrated. Honestly, starting Point Guard is the one position I have zero complaints about whatsoever. He's the most reliable (still good) player on the team. Last dude I want to trade. Even for Rondo. Rondo's extra few assists doesn't make up for the loss of offensive punch that the other Spurs have been playing off of anyway.
How'd Parker get exposed?
He held Westbrook to 18 PPG/37% shooting for the series. 7.3 APG, 3.3 TOs/game
Parker put up 21.5 PPG/48% shooting for the series. 6.3 APG, 3 TOs/game
Parker handled him. Nothing got "exposed". You're just only remembering Parker's 2 mediocre games and forgetting the good ones. Westbrook only had 2 good games and of those 2 good games, Parker had an even better game than Westbrook and OKC was 1-1 in those 2 games.
Parker made Westbrook, the supposed "better PG", the inferior PG. He gave the Spurs an edge at PG. Stop playing revisionist historian because he didn't completely destroy him. Parker still out-played Westbrook.
