As a native of Chicago there's much I can say about how Cubs fans are often at Wrigley for the "scene" and White Sox fans are at the game to watch a game, but I'll decline the temptation. I'll simply say that every few years we become 100% convinced that Bryce absolutely wants to play for the Yankees because he grew up idolizing Mickey Mantle, or that he absolutely wants to play for the Dodgers because his family is up west, or that he absolutely wants to play for the Cubs because his best friend in the whole world is on that team.
Sounds like even if he has strong desires about where he wants to go, these are fickle and could still change in the next year. Or, more likely, there's a bunch of places he'd consider playing for various reasons, and he'd be OK with going to any of them if the price is right. Washington might even be one of those places.
