So what we have here, is a guy who at every level, does not allow hits, strikes out a ton of batters, and never allows runs. The consensus is clear. If he develops his slider to a mediocre level, you are looking at a pretty decent starter. At worst, he'd likely make a very good RP, and he could probably do that right now.
So I don't get why you guys pick on Rudi. This dude is a pretty good looking young pitcher who just gets guys out at every level, and who everybody agrees is a legit top level prospect if he improves his slider.
