At the Supporter Summit MLS and USSF admitted that they weren't doing enough to improve the standards of refereeing in the League. They continue to improve their ability to self critique having regularly called out their CRs and ARs for wrong calls.

In this clip, the AR incorrectly calls an attacker offside from a long, diagonal pass into the penalty area. This decision, takes away an attacking opportunity. Image 4 shows the relative closeness of the positions of the attacker and the second-to-last defender. This is a perfect candidate for giving the benefit of doubt to the attacker.

The AR is well positioned to make the call (as Image 4 illustrates) but must show restraint in raising the flag. Total concentration on the offside line and the ball (at the time it is passed by the attacker’s teammate) must be practiced

One bad call early in the match may have changed things, but I find this case unlikely to do so. It would have certainly helped in Goal Differential (Seattle has lost two goals now on bad calls admitted by the review) and if Seattle was at 10 GF in 8 played they wouldn't seem quite as inept.

Jeremiah noted this call in his deep look into the match by the way.
