JWash's game is nowhere similar to Manek in style alone
I get what you're saying but I can't help wondering if it just looks that way because we don't ask JWash to play more like Manek.
Put him at the top of the arc and get him the ball. Let's see what happens. If he makes those shots, that could be a game changer.
If that doesn't work, I guess you just start bringing him off the bench.
I notice that in AJ's recent video, he also suggests trying Lubin in the middle and JWash at the 4.
Maybe not a guaranteed improvement, but certainly looks worth a try.
