MetroFanaticDan might have to confirm my figures on this, but as of this weekend's draw at DC, "New York Red Bulls/Red Bull New York" have played 15 fewer competitive matches than "NY/NJ MetroStars/MetroStars"
Metro: 352 total
MLS Regular Season: 306
MLS Playoffs: 19
US Open Cup: 21
International (Mecronorte): 6
Red Bulls: 337 total
MLS Regular Season: 292
MLS Playoffs: 22
US Open Cup: 17
International (CCL): 6
Assuming that count is right, sometime in July, depending on how the Open Cup goes, the franchise will have played the majority of its competitive matches as "Red Bulls."
Make of that what you will. The facts are the facts.
