This made me chuckle. Thanks for the laugh. Can you point to an example where a staff ace and CY winner was traded for an all projection SS prospect that hasn't played pro ball? That's rhetorical because I already know the answer. Mayer is going to fail and never see the light of day in MLB. My projection has more chance of happening than yours based on the odds. Rocchio is a better SS prospect than Mayer.
Remember even Chris Sale, who was better than Shane Bieber, got only Yoan Moncada. And while Moncada was an elite prospect, the difference was he wasn't a SS, he was a 2B/3B.
Not recently because SS prospects of Mayer's caliber never get traded. Turner, Seager, Correa, Bogaerts, Lindor, Story, Baez, Machado...teams hang on to these types of prospects for the very reason I said: if they pan out they are insanely valuable. You illustrated my point. Even really good starting pitchers like Bieber don't fetch a potential franchise SS. Team's will hang onto those guys over pitchers because pitchers break so easily. One day they are good the next they need Tommy John. So you never see it.
