The jury is still out on a few possible "burns," but yes, it looks like no trade was a clear "killer." Even if Moncada and Kopech turn out great, Sale did very well for us. (Note: I don't count the extension as part of the deal.)
Yes, bias and optimism play roles, but there seemed to be less optimism on the very highly ranked prospects DD traded than the lesser ranked prospects we have now, maybe even by some of those who were fine with all the trades.
I'm sure glad DD chose to hold onto Devers, and I felt that way from the start. Injuries to Espinoza and others have made those deal look better, and flops like Guerra have, too.
We certainly could not get the same sorts of returns from our current prospects as we did from the two dozen or so DD traded away, and maybe that plays into the "hold em" mentality that seems to be prevalent, these days.
Going by MLB Tradevalues numbers, here is how our prospects are valued:
#44 Downs 26.4 (15 prospects have a value 2X or more)
#52 Casas 22.2
#66 Dalbec
#106 Mata
#109 Duran
#152 Jimenez
(No more in top 200)
If one figure we should have 1 in the top 30, 2 in the top 60, 3 in 90 and so on, it appears like we have more than average in the top 60, 90, 120, but less than average in the top 30. (Exactly average in top 150.)
Maybe once the PTBNL'ers are known, and maybe guys like Potts or others get more of a chance, these numbers may improve, but when you look at some of these other team's rookies they are calling up, my jaw drops, and I can't help thinking, "Where's our can't miss guy like that?"
