We can just say impact = well above replacement level. Kremer is a great guy to have as our #5 as he would have been on Opening Day if not for the aforementioned starter injuries. I'm sure no one really thought Bradish would be AL Cy Young-4 in his second year in the MLB. That's a fantastic hit by Elias. That and getting Gunnar in the 2nd may be the most impressive things Elias has done?
To answer your question, no I probably didn't think much of Bradish when we got him as an A Ball pitcher. Would I have bet he individually would be elite? No. But would I bet there'd be an elite pitcher in all the pitching prospects we got back for Manny Machado, Zach Britton, Jonathan Schoop, Kevin Gausman, Darren O'Day, Dylan Bundy, Jonathan Villar, Miguel Castro, Jose Iglesias, Cole Susler, Tanner Scott? Well I'd hope so. Out of them we got Bradish, Kremer, and Tate (1 elite SP, 1 decent SP, 1 reliever and a bunch of names we've forgotten). I'll take it. We'll see what we get any SP's out of the Trey Mancini and Jorge Lopez hauls.
Now we're in a different position where we aren't selling off assets to get back dart throws. At this point, our conversation will get circular but it will take value in prospects or value in dollars or some combination of both to get more elite talent in the rotation. Don't expect to give middle tier contracts out and get back elite level performance. And I don't think we'll be able to maintain this ridiculous level our farm system is at forever. And we won't be able to have the luxury of sending off 12 years of Joey Ortiz and DL Hall type players for 1 year rentals every year.
