It depends what the floor is. People got all over the Marlins for fielding a very young squad, whose salaries were low, but comparable with those of similar players on other teams. Nonetheless, they were competitive, and the team reflected a clear and onsistent plan and vision, which many of the big market teams lack because they can bury their mistakes and myopic judgment with cash.

While baseball revenue has increased incredibly this decade, a salary cap is needed to even the playing field among the individual teams. The luxury tax didn't solve anything as the gap between the haves and have nots grows.

The team revenues must be examined and if there is a cap, a portion of
profits that exceed a certain predetermined figure should be divided on a share(based on salary) among teammates and coaches.

Football excels on a system where gate receipts, tv money and merchandising are split equally among the 32 teams.
