You do kind of realize that you asked how often one finds power pitchers in the draft after the top 50. I said often and pointed to the Phillies current rotation. So it really does not matter if we drafted them or not. There is a decent track record of Phillies' overslot HS pitcher signings like Ryan Madson if you want to point in that direction.
This is just another post of "what-about-isms". My point was that these soft-tossing college pitchers who succeed are a dime a dozen. So why draft them when you can sign them as minor league free agents? Nobody actually argues against signing a bunch of Latin American projectable pitchers. You seem to be the only one arguing against drafting projectable HS and college pitchers for some strange reason. It is actually the same logic about signing the Latin American pitchers.

There are quite a few HS arms in the top 10-15 rounds that make it. Failures too of course. But the success rate is probably as good or better than college arms beyond the top few rounds. And low ceiling college arms in the top 100 picks may make the majors because they have little risk, but they are usually not that good and pretty replaceable.
I am really looking hard to find your point. Vance Worley is about the most successful college arm we drafted and signed outside the top couple of rounds in the past decade and he kind of makes my AAAA point as he has been released multiple times. We need to sign more HS arms outside of the first round. Klentak actually started doing that a bit more this year. Good for him.
