A current prog team of mine with below average AAA landed 1983 Byran Oelkers, an actual 200K scrub (35 innings, ERC# 9.59). I've never had a rookie that bad before. Then again, according to Merkle's AAA - Just the Charts thread, below average rookie starting pitchers range from 200-950K (200-700K for relievers), so maybe it's not that the rookies are getting worse, maybe it's just bad luck.
