It's not just injury concerns, though. When pitchers throw a ton of innings, they tend to lose effectiveness as well, even if they don't get hurt. Look at Z for example. He's thrown over 1,800 innings in his career and just had his worst ML season with peripherals that make him look very questionable going forward. He's also a year younger (30) than Wilson in 2011 (31). He's not had injury issues, but even though he's still young, he's getting ineffective - and it's largely because he's thrown a huge amount of innings. Abusing a pitcher's arm doesn't necessarily simply make them more likely to get hurt, it damages their effectiveness. There are certainly exceptions (CC), but if I'm going to give out a big money deal to a pitcher, I'm going to feel better giving it to a guy who doesn't have a ton of wear on his arm because the chances are better he'll remain effective throughout his contract. Another encouraging sign for Wilson is that while he's only had two excellent seasons (out of 2 total starting), his peripherals have improved from year one to year two. His K/9 went up almost a full strikeout (7.50 to 8.30), his BB/9 dropped more than a walk (4.10 to 2.90) and his WHIP got better (1.25 to 1.19). None of his numbers were boosted by luck, either, as his HR/FB ratio actually went up (5.3% to 8.2%) and his BABIP went up (.266 to .287). Granted he doesn't have the long track record of Prince or Pujols, but I'm not advocating giving him $20+ million over 8-10 years like has been advocated for Prince and Pujols. My limit has been 5/85-90 with the possibility of a 6th year option (vesting, ideally). His camp beginning negotiations at 6/120 backs that hope up, as it's almost a certainty they'll get less than their initial demand. Keep this in mind as well - Cliff Lee had three excellent seasons before signing a 5/120 deal. Wilson has had two before his big deal, however he has not had the complete ineffectiveness Lee had prior to his breakout. Wilson might just be a better gamble at a lesser cost than Lee was.
