If describing Boston in 2022, needlessly is a needless word.
The M's are in go-for-now mode, and not just because they're the only team never to play in a World Series. They have a deep pitching rotation in place, with some controllable studs, and more importantly, coinciding with young stars at positions. The time was ripe for a Castillo trade.
Boston finished last, and has holes all over the roster. The Sox may have a ways to go before they're ready to deal their own #1, 3 and 5 prospects for one pitcher. Remember, when they traded for Chris Sale, they were already a first-place team.
