The Red Sox owners have made piles of money on the increase in the value of the franchise.
As far as the profit or loss for 2019, only they really know for sure.
We know they had the highest payroll in baseball and paid 13 million + in luxury tax for an 84-78 record.
JH's general message seemed to be that he didn't mind spending to that level for a championship team, but for an 84-78 team, not so much. Especially when the Rays spent a fraction and won 96 games.
