There's nothing incompetent about PATFO. They've had priorites and have done a of a job with this team. The last two years they've had to get talent (LMA) to put next to Kawhi, resign Danny, Kawhi and rebuild the bench. Then last year they had to find a TD replacement and rebuild the bench yet again. Both those were higher priority than Tony (and even so two recent #1 picks Murray and KA were point guards). The fact that we're contending shows they've done well. Now, is it time to address, sure. But it was a reasonable hope that Tony could hang on until those other needs were addressed or that Patty might become starter-worthy or that one of Murray, Forbes, KA, or Simmons would blossom into a keeper in the guard rotation.
The mentality on this site is always - "If the team has a weakness, someone in the front office, must have screwed up." i don't agree. Just maintaining contender status takes a of a lot or work and a little luck. RC has done as well as could possibly be reasonably expected.
It is a shame a few years ago when Tony was at the tail end of his prime (and making All NBA teams) when we had TOO many pgs in the line: CJ, Decolo, Patty, Neal. Now, the cupboard is bare but its not incompetence, just simply you can't solve all problems at all times.
