I understand your points while I disagree with them, Seager's injuries are quite concerning and there's no guarantee that he'll even get back to the level where he was at in his first two years in the league.
The bolded holds no basis though, Baez's PD stats have not changed in any way to indicate that a boost in walk rate is coming, as a matter of fact he's actually swinging at pitches outside the strikezone at a career high rate, one that continues to trend up with every year that he's been in the league. This is who he is, an aggressive hitter with prodigious bat speed which results in excellent contact off the bat, but which makes him prone to swing at every pitch believing that he can hit it.
