the vast majority of players who completely flop at the big league level (over the course of a full season) do so because they're just not good enough or can't make the necessary adjustments against big league pitching, not because they're too young or whatever. i don't care if ronny was 23 or 33, his performance in 2006 showed there was a strong chance that he could not become an adequate major league player. soto and hoffpauir weren't given the chance at age 23 because they had not seemingly mastered lower levels of play, as it seemed that cedeno had. but once you've done well against AAA pitching then you should be ready to face major league pitching. age really doesn't matter here. your "argument" is bad. you realize your quotation marks make absolutely no sense whatsoever there, right? why doesn't age matter here? b/c you said so? And anyone that has 1 good season at AAA is ready for ML (regardless of age), and if they don't succeed, they should be completely written off. Even if they go back to AAA and dominate again? yeah, ok.
