"90%? 84.6%"
Sure, yeah, whatever. My point is, i would expect $20m scouting budgets to be largely accurate. I would expect some players to fall short of their expectations, some to meet expectations, and some to exceed expectations.
"I don't keep records of what my scouts said they'd be on draft day."
This makes me wonder why you feel qualified to comment on this if you don't even keep track of how often players reach/exceed/fall short of their potential. I do keep track of these things. You don't. Who do you think would be more qualified to comment on the matter?
"In real life, lots of first round picks become massive flops."
Absolutely. But in real life there would also be a number of really late round draft picks who would become HOF level players. (Greg Maddux, Albert Pujols, Ryne Sandberg, et al.) There would be plenty of players who would EXCEED their projected draft-day ratings. Please note I capitalized "exceed", as I keep mentioning it and you don't seem to be willing to admit that players rarely, if ever, become better than their draft-day potential.
