That's a good assessment, and I often am critical when people make judgments based on small sample sizes, but I was really impressed with Early's approach, confidence and control of several pitches. It might have been an outlier, but I kinda like Early and Tolle about the same.
I do think Tolle has more upside, but it's the "lower floor" that worries me. I'd like to keep both by trying to include 1-2 pitchers from this group instead, but GMs may balk at the offer:
Crawford & Perales
Dobbins & Fitts
Harrison & Clarke
(Mix and match)
So many teams need 2-3 SP'ers that maybe offering quantities of promise could outweigh a solo, high upside pitching prospect.
Duran plus any 2 of the 6 pitchers I listed should net us an excellent SP'er.
I'm not sure Duran, Fitts plus 2 from these guys gets the same pitcher:
Fajardo, Valera, Sandlin (maybe Witherspoon/Phillips added in this mix choice)
