I think you're way overvaluing how much an int'l prospect signs for, especially if they have the same numbers in the minors. Like, if both their numbers are garbage, then who cares? They both suck.
Brito had a K rate of over 30% in rookie ball. Chances are, he won't ever be anything. Still an understandable move though, if he ever does cut down his K rate he could be a guy. I just won't hold my breath.
