Well, Kay and SWR were acquired for Stroman (at age 28) who had a year and a half of control left and a 3 WAR in 124 innings at the time of the deal. The Jays weren't dealing anyone like that this deadline. If they were, then I'm guessing the return would have dwarfed the Stroman return from 2019 based on the market. The better comparable is Drury/McKinney vs what Kikuchi got; one was considered a heist, and it wasn't the Happ deal. That doesn't mean Bloss, Loperfido, and Wagner will pan out, they may all stink, but at the time of the trade it's a better return.
As far as the rest of the deals, it's all subjective and since most prospects will fail or cease to be heard from again, it's pointless to debate them individually, but I'd easily take this deadline over 2018-19. I do think Atkins did really well in 2017 though, as Teoscar (even without hindsight) was a great return for Liriano who was a rental and awful that season.
