The single biggest improvement MLB can make to competitive balance is to restructure the playoff system, as the article suggests. Let's compare to the NFL. Each individual team is only competing with three other teams for a division title. And if they don't win the division, there's still two chances to win a wild card spot. In MLB, most teams are competing with 4 other teams (or in the case of the Brewers, 5 other teams) for that division title, with only one chance to get in as a wildcard. On day 1 of the season, any individual NFL team is more likely to make the playoffs than any individual MLB team. Regardless of salary cap, coaching, revenue sharing, or any other factors. Plus, in the MLB, there's a greater disparity between the winning teams and losing teams, so if MLB expanded the playoffs, they probably wouldn't have the NFL's issue of teams getting in without posting a winning record.
