I think it's time for a breakaway MLB Super League for the owners who want to spend/invest. It will obviously never happen but I totally understand what the European soccer clubs are trying to do. If owners like Cohen come to a conclusion that they can make more money by breaking away from the likes of the Pirates, Reds, Marlins, A's etc...
I have mixed feelings on it.
Let's be honest, as fair and noble as revenue sharing and the luxury tax are, baseball was just way better and way more intense when the Yankees, Red Sox, Mets, etc. were just in an arms race trying to outspend each other as salaries skyrocketed. I think what the Mets and Padres are doing this offseason is pretty awesome and will make for a more entertaining product on the field. But we don't want the competitive balance to be so tilted that teams like the A's collapse outright and teams like Tampa become feeders to the big clubs like the old Kansas City Athletics of the late 1950s.
In the current system, with good management and a little luck in drafting, any team in the league is 3 to 4 years away (or less) from being a contender. Draft a superstar, or make a big trade for one, take a splash in the free agent market, and you can make a run (especially with the expanded playoffs). That path is open to everyone except Oakland, who are kind of just a grift at this point. If you loosen the rules and regulations, the haves will swallow the have nots whole. The Yankees, Sox, Cubs, Cards, Mets, Braves, Dodgers, Padres, and Giants will go out of control with spending and leave the middle-of-the-pack teams like Minnesota, Milwaukee, Colorado, Cleveland, etc. behind.
The superleague would be very fun and make high-level baseball amazing. But it'll cripple competition and such. It's like the EPL, how unrestrained capitalism has just let it be 4 to 6 teams who run the whole league and the rest are kind of just there and I'm not entirely sure how they maintain fanbases. Like if you're a low team fighting for promotion/relegation that can be exciting, and if you're a top team competing for one of the slots in the European tournaments, cool. But if you're in that 8-14 range in the table like Aston Villa or Crystal Palace, like what's even the point of getting excited enough to watch, you're kind of sitting there trying to be good enough to attract an Arab trillionaire to buy you out as his new plaything and bump you to the next echelon.
