Put it this way: McNeil could see a Yelich-style jump in his power stats. Smith might also benefit. Davis becomes a right-handed bat to slot between Yelich and McNeil. They all had an OPS+ of 134 or better. For Hader and Lutz... a good return. A 1-6 of Urias, Hiura, Yelich, Davis, McNeil, and Braun is not bad. I'm afraid you are vastly over-rating Mr. Jeff McNeil. Especially his power potential...He only had 28 HR in over 1600 minor league at bats and he will be 28 years old already in 2020. Or perhaps you are underrating him based on him minors numbers? I mean, the guy has an excellent 1 1/2 seasons of MLB time so far. And who cares that he's going to be 28? It's all about cheap control, and he has a lot of it.
