It's fine. Sure, people have some preferences for some players (like Gio Reyna - 19 yo, plays at a German powerhouse club - Dortmund). Typically, a lot of the complaining happens when MLS players are playing big roles when there are available players that play in big leagues in Europe. If Jordan Morris started this match, there would be an uproar (justified IMO). Morris had a chance to go to Germany's top division, but chose not to because he and his GF got a new dog and he was comfortable in Seattle (MLS).
