From an AP report, MLS commissioner Don Garber cited cost as the major reason for not implementing technology:

GoalControl said it is likely to cost about $260,000 per stadium to install, and $3,900 per game to operate. Speaking Thursday to the Associated Press Sports Editors, Garber called the price “very, very, very expensive.

“It had us take a step back and pause and try to figure out is the value of having goal-line technology worth investing millions and millions and millions of dollars for the handful of moments where it’s relevant?” Garber said. “And our view has been that we’re going to wait and see how it works out. We certainly don’t need to be the first league that has it.”

He said it was a matter of “prioritizing how we spend our money.”

There is another reason why GLT would be silly in MLS: there’s no real reason for it in a league with strict centralized financial controls and where half the teams make the playoffs, at which point anything goes. There is no major financial cost to missing out on the upper places in the league.

To some degree, MLS has its priorities straight. Football is supposed to be a game, not a high-stakes financial gamble where millions are won or lost on each goal. That’s really stupid, in a way. Exciting for the neutral no doubt, but stupid.
