Post Ohtani, I'm really all in in one beefing the hell out of the pitching staff. Something like Glasnow, Imanaga, Robert Stephenson, and Tanner Scott. You'd be looking at a pitching staff of:
SP - Steele, Glasnow, Imanaga, Hendricks, Taillon
RP - Adbert, Scott, Stephenson, Merryweather, Leiter, Smyly, Cuas, Assad
That is a fairly monstrous pitching staff, particularly when you think about how much talent is down at Iowa ready to step in for injury.
Eyeballing it that would project to 18ish WAR, which would be 3rd on Fangraphs behind the Phillies and Braves. And between the youths and the conservative estimates on innings for Glasnow/Imanaga there's plenty of additional ceiling.
The above is $55-60M, which might limit you to only one bat of consequence. So maybe swap Stephenson out for more of a Hunter Harvey type? But regardless I don't think it takes a ton to keep the offense flat-ish with last year, and there is more than enough quality pitching available to put together a staff that will absolutely embarrass any non-Braves lineup.
