I'm on team full rebuild, no shortcuts. 2023 at the EARLIEST and only because so many of the prospects they received at the trade deadline are ML ready or close to it. The Astros rebuild and Cubs rebuild, both of which resulted in World Series runs and years of postseason appearances, took about 4 years each with really bad teams in the interim. Attempting to compete in 2022 would be a huge mistake: the likely outcome would be a team that is merely mediocre and wins nothing while getting a crummy draft pick. The 2022 Nationals should be a terrible team that competes for #1 overall pick with the likes of the D'Backs and the Orioles. The money would be better spent by the Lerners investing it elsewhere until they sign the 2024 equivalent of Jayson Werth to the Nats or Jon Lester to the Cubs.
If you must spend money, try to sign the obvious rebuild pieces like JoJo Gray to long-term extensions now. This buys more time for the rebuild to truly take place and bear fruit as well.
