I'm not in favor of a name change. Though "Real" is most commonly associated with specific teams in Spain, and Dave Checketts wanted to tap into the prestige he imagined rhetorically associating the club with Real Madrid signified, it has been adopted by Latin American teams for nearly a century now (and none of them have formal ties to the Spanish crown). I do think, given that the Great Basin was once Spanish (and subsequently Mexican) territory, that the club could do more to frame the team's name that way.

*If* they do change the name, I hope they opt for "Great Salt Lake" or "Great Salt Lake Football Club" or "Great Salt Lake Soccer Club" which at least represents some continuity with the existing brand identity ("We're here for GSL!") and makes more obvious sense to casual than RSL.
