I don't know. Last offseason and early in the season, I heard the likes of Longenhagen and maybe Law (not sure if it was Keith or someone else like Szymborski) really talking up the upper levels of the Cleveland farm and how they were going to get scary-good, scary-fast. There were rumblings that most of baseball was sleeping on Cleveland's organization a bit.
While I really like Milwaukee's hitting prospects, I haven't heard similar rumblings about them. Naturally, that doesn't mean the Brewers can't burst out with a bunch of rookies, that's always possible, but it's a dangerous way to build an Opening Day roster.
