OK dude, three things.
1: Pomeranz' durability issues are overblown. People who are saying that this year's 100 innings are the most he's ever pitched in a season are ignoring minor league innings -- while they don't count in some areas, you HAVE to count those when discussing durability. In 2012, Pomeranz pitched 144 1/3 innings between the bigs and the littles. That means in theory that getting up to at least 170 innings isn't going to be a substantial risk for him even if he was 23 instead of 27.
2: Comparing Pomeranz directly to Buchholz ignores the many areas in which the two are very different. Pomeranz' issues are not related to the same factors that plague buchholz. For one thing, Pomeranz doesn't have anywhere near buchholz' injury history. Pomeranz' lack of innings pitches is a matter of role, not a matter of injury or incapability as has been the problem with Buchholz. Yes he struggled in the funny physics of Colorado's high altitude stadium as a young player, but that was 4 years ago, and in the meantime he's put up decent numbers in a swing role, and took a step forward at age 27 -- not that unreasonable age for a pitcher of that high status as a prospect, to take that step forward.
3: One thing I'm looking forward to out of Pomeranz is at least some chance of being healthy and effective in the playoffs. If buchholz had ever once given us at least that much, I'd be a lot less hard on him. Pomeranz has also done at least one thing that Clay Buchholz has never EVER done in the big leagues -- pitch effectively IN his role FOR a full season WITH a minimum of drama and catastrophe for THREE straight seasons.
