In one week near the end of September, MLS' Philadelphia Union traveled to New York City and back, then across the country to San Jose and back home before it went westward yet again to Columbus.
Union star Alejandro Bedoya injured his quadriceps in that third game in eight days and called it his career's first muscle injury.
In that time, he flew cross-country twice in economy class and sat on a bus in traffic between San Jose and San Francisco for two hours the morning after a game.
"I do believe if we had flown charter directly after the game in San Jose, that could have prevented my injury," he said.
That's why Bedoya — an MLS Players Association bargaining-committee member — has endorsed in labor-contract conversations with owners that MLS joins major sports leagues in making chartered air travel standard.
It's one of several issues discussed in negotiations that will intensify now that the MLS Cup is over and Tuesday's expansion draft is here — and long before the current five-year deal expires Jan. 31.
Money, as always, is at the forefront. But the players' union also seeks what it calls "true" free agency, simplified salary-cap mechanisms and rules, compensation that rewards current performance and better travel that improves performance and turns current travel days into practice or regeneration days.
Players Association executive director Bob Foose calls this go-round all about a partnership that transforms MLS into what Commissioner Don Garber long has sought: a "league of choice" in a global game.
