Anyone who assumes they know anything about a pitching prospect has simply not followed pitching prospects very long or very deep. Predicting a top 5 pick is as tedious as predicting a 12th rounder. It's absolutely amazing how random baseball is. One of the best arms I've ever seen going into a draft was Luke Hochevar. He blew threw the minors in 2006 and if you adjust for league, his 2007 numbers in the minors were quite solid as well, but he just wasn't successful as a starter in the major leagues. That said, he's made a very successful conversion to the bullpen, assuming a successful return from TJS. Bryan Bullington was another one that watching at the time would have assumed he'd be at the very least a solid mid-rotation starter, but he was picked #1 in a draft that had a first round of guys like Zack Greinke, Cole Hamels, Matt Cain, Scott Kazmir, and to a lesser degree, Jeremy Guthrie and Jeff Francis. Yet Greinke was the highest-drafted of that group as the 5th pitcher picked in that draft, 2 of which never even made the majors. I can't speak on Chris Gruler, who was injured and never made it back, but Clint Everts, picked right ahead of Greinke, was a Texas fireballer that was rumored to be in the mix for #1 due to his high upside arm, yet he's now a reliever in the minors who's never cracked a major league roster. This postseason is showing the value of high-end relievers at the back of the bullpen in the modern game, and it is possible that Meyer may have more value as a top-shelf reliever than he would as a #5 starter. That would not be a failure whatsoever in the grand scheme of baseball, and certainly not a failure in the scheme of pitching prospects.
