They see the writing on the wall. Only a matter of time before MLS clubs can pay as much for the top talent, if not more.
I am the biggest MLS fan-boy there is (season ticket holder, travel to other stadiums when my team's not playing for fun, watch half a dozen games per week). This is never going to happen.
I think for MLS, continued success looks like this:
1 - 20-25K butts in the seats each and every game, with one-offs like Atlanta and Seattle playing in NFL stadiums maintaining their current 30-60K attendance.
2 - Stadiums being built within the City limits of New York, Dallas, Boston, and Chicago. All on major public transit lines.
3 - Continued academy investments. Each and every year for the past 5 years or so, we've gotten bigger moves coming out of these MLS academies - Bayern, Dortmund, Gladbach, Schalke/Juventus, RB Leipzig and Salzborg, etc. What we are not necessarily seeing yet are the players just below the Chris Richards, Gio Reynas, etc who are breaking into MLS first-teams now but aren't quite top-level Euro players. These guys will ultimately elevate the league to its next level.
But the issue is it's still such a saturated market. Watching Liverpool, Barca, Roma, whoever on Saturday and Sunday mornings has become part of US sports culture. Unfortunately, MLS are offering Mr. Pib when Euros are offering Dr Pepper in this market.
Their issue will always be how do you convince fans to switch. I think the good thing is that they have a few real advantages in the US sports market though. I think you get a better outdoor fan experience at MLS matches than NFL or MLB games. I love that kick-off to final whistle is under 2 hours which makes it an excellent family outing. And the tickets are generally significantly less expensive than other sports.
The great thing is, we don't need MLS to be the EPL to be excellent on the international stage, we need it to just keep expanding our player pool and getting players to major clubs like its been doing at an accelerated rate over the last few years.
