Maybe I'm a wishful thinker, but I expected Smith to struggle for a while. I think we will improve. Yes, Thornburg's return is not something to count on, but there is a chance he and Smith can take up the slack left by a departing Kimbrel.
Of course, we'd be better with all 3, but since Smith and Thornburg have given us nothing, so far, once could hope that both could replace Kimbrel next year, and it's not robbing Peter to pay Paul.
Replacing Pom might be harder, but right now, we're on top of MLB without Pom helping at all. Perhaps losing him won't be as bad as we thought in March.
I know we'll need a lot to go right. I agree that we need to not let HRam vest, but I still think the "window" is wider than many feel it is. To me, it is 4 years: 2017-2020. Maybe this year, on paper, is our best chance, but I like our chances the next 2 years as well.
