Sox did spend $239M (2018) and $243M (2019). Cot's has Sox at $35M under the current $210M cap (Vaz option not picked up).
At $240M, we potential have $65M less $7.5M for Vaz or say $57M. If JD opts out, that will be close to $80M available. Trade Xander, sign Semien, Schwarber, Correa and a starting pitcher. Price, Eovaldi, Kike, Vaz money all come off after 2022 for combined total of $48M.
Be bold, think big.
