Teams do this, it's legal. But the Brewers are bush league, I wouldn't put anything past them, I don't like the way they operate, but they're also not alone. They do seem very good at gaining value on the fringes, legal or not.
Jed and the Cubs players seem like a group of really good people, and i suspect it's at least partially by design led by Jed. Maybe they're even too nice for this era? I dunno, but they can probably hang their heads high. I'm proud of them no matter what happens.
