For this idea, I'm going to assume all free agents and option players are gone, except Story.
We trade Rafaela ($48M/6, but $6.3M AAV) & Crawford (3 arbs left,) for Mitch Keller ($55M/3, but $15.4M x 3 Tax line) We add about $6M to Tax line.
We trade Campbell ($59M/7 or $7.5 AAV,) Sandlin, Paez & Hicks ($24M/2 or $10.3M AAV) for Ketel Marte ($91M/5 or $19.4M x 5 AAV) We add about $2M to Tax line.
We sign Schwarber at $32M x 5. ($32M AAV) and non tender Lowe.
That's $40M added AAV. The roster... (40 not 26)
