They threw 75 miles an hour
Funny, but not close to a good answer.
It's gotten to the point of why draft starting pitching at all? Certainly not with your top picks. Might as well just take your chances with "surprises" from lower positioned picks, good fortune with your international scouting, and the trade market where you have a better idea of what you're getting.
Starters only pitch for you every fifth day and then hopefully give you, what, 5-6 innings? Then, you face all sorts of physical breakdowns requiring questionable long-term surgical intervention, years'-long recoveries, prognoses for contract out-years that are crap shoots, etc.
If I were a GM, I'm looking at the odds and taking my chances at the top of the draft with everyday position players.
