As BlueRocky said, college players, especially pitchers, have never been better. And with the rise of technology in college baseball programs, there's more to base the scouting reports on. And "major league teams do pay for access to college TrackMan data, and many of them weight it heavily in their draft models."
But there's no such thing as a pitching prospect. First, you have the injury risk. Second, the change in usage patterns (last year only 15 pitchers threw 200 innings or more; 13 the year before) has drastically reduced the value of a SP. With your top draft picks, you're hoping to get a 'franchise cornerstone,' someone who's going to be the star of your team, and starting pitchers just don't fill that role anymore. The jobs of Starter and Reliever are blending together at this point. The fact that only 3 HS pitchers were selected in the first round last year—the fewest since 2008—is a real trend going forward.
Add on the very inevitable TJS and it's easily Veen/Mitchell over Lacy/Hancock for me.
