Yes, and "down the road" is the same as hindsight. Several of these down the road prospects books are not complete, yet, and many of the players we got already have their "books" competed.
I don't see many chances for anyone we traded to suddenly jump on the map, but we also have to look at total years of control of the players we traded vs the limited years of control of the players we got.
Take Margot, for example. He was traded in 2015, but did not really start playing FT until about 2017.

Comparing to our OF'ers at the time of the trade (2015) may or may not be "fair," but here are the numbers:

I won't post Betts, because we know he blows Margot away.
