If we fail to make the playoffs, I'd trade JBJ and reset the tax. I'd look for a 1 year rebuild and try to keep Betts after 2020.
Porcello, Moreland & Pearce would be gone.
We might not suck in 2020, because we'd still have Betts, Devers, Bogey, JD, Vaz, Beni and 4 rturning SP'ers, but I wouldn't spend a penny over the first tax line in 2020.
