If the infield is the position group most in flux (with the most boom or bust potential, as well), and catcher seems stable but not exactly star-studded, the outfield not only seems pretty set, but is our best positional group by far. As a group, the outfield is likely to be comprised of our most impactful bats, our best baserunners, and likely our best defenders.
In fact, the only problem we have is that there are only three defensive spots for our outfielders. Of course, I will make the case for one of them—one who has more than paid his dues—at DH in this post, as well.
