That would be terrible. One year of a guy who isn't even an ace and whose innings jumped by a tremendous amount this year. . Wilson has a 3.10 ERA despite pitching his home games in the best hitters park in the AL. He's more WAR this year than Fielder. The innings jump risk is a completely unproven theory. I don't believe in it, and niether do the Brewers. Oh boy, where to start. First, I would love to see any kind of evidence you can find on why the Brewers don't believe in the "innings jump risk" as you put it. I wonder why they limited Yo's innings last year since they don't believe in it. Second, I am pretty surprised someone would use ERA and WAR in the same post. The only reason to do that would be to further help your argument, since if you bothered to look deeper you would realize Wilson has been aided by a BABIP of .262 while his strikeouts are down and his walks up from being a reliever. As TooLiveBrew said, everything about his season screams career year, and even then it is not ace caliber as you alleged. Third, Wilson has more WAR this year than Prince? Are you using Baseball Reference's crap calculations instead of Fangraphs? Wilson has 3.8 WAR this year (good no doubt) but Prince is up to 4.0 now and will likely keep adding to that while Wilson will most likely tire as he nears 200 innings. Add to that, their total WAR over the last 5 years (2006-2010 when both of them started being MLB players for good) and its not even close: Prince - 20.2 | Wilson - 6.6. I'm sorry, I don't really think your trade proposal is likely or makes sense for either side. No reason to argue with me by making stuff up, you are not going to change my opinion or anyone else's that way.
