I think that's a built-in assumption, as well as the assumption that Corey Seager is a better pure hitter (in terms of AVG, OBP, wRC+) over the long term. Jim wouldn't have done this trade if he thought they were exactly as good as one another going forward and I wouldn't have done this deal if Seager was healthy and helping me win this year. I do think there are some red flags about Seager that some may be more willing to gloss over, and I also have a higher tolerance for Ks than some owners. It's entirely possible that Baez' power breakout will lead to increased BB rate over time and that Seager's injuries will deplete his power and make him go down the Joe Mauer/Buster Posey path. Or Baez could pull a Marcell Ozuna next year (BTS' comp) and Seager takes a Mookie Betts style leap into the stratosphere. There are a range of outcomes at play here. I just know I am an impatient man and Baez can help me a lot this season while Seager can't, and I'm willing to roll the dice that they could possibly be equal (but different) fantasy players going forward.
