We haven't had "a young talented player that is superior to the old vet" - even Favors admitted he didn't deserve to play ahead of either Millsap or Al Jefferson, and he was closer to being a starter than either Kanter or Burks was. And has been pointed out already, Burks has been taking (as in "earning") minutes from the "old vets" as the season has progressed, and this year (unlike last year) his level of play has merited this. Kanter, on the other hand, has been poor most games.
Also, the anti-vet crowd is ignoring the fact we we gave both Biedrins and Rush a chance to produce on the court, but have benched them for their non-production, and thankfully JLIII has been given the hook in favor of Garrett. So it's not like being a vet is a golden ticket.
The message is we play players who deserve minutes, and we won't treat players like the Hornets treated Kaman after they traded for him, to use one example.
EDIT: Okay, it was just Millsap he mentioned specifically as being better than him:
