We getting back a decent backend starter, it's a good trade when you look into it
No it's not. Megill is a better #5 option than Paddack. Pagan has declined and Hosmer is not a starter on a contending team right now. Unless they flip Hosmer but at that point what do you think you're getting back?
At least with Smith he can play 1B more than adequately, and LF in a pinch and is not a total butcher out there. You're also selling low on Smith especially after we know he was hurt last year.
