That "usl team" was named team of the decade by MLS
MLS team of the decade went to Seattle, with LA Galaxy as the runner up.
NYRB were 2nd runner up of the decade, which just about sums it up: not even first among the also-rans.
Not even Grelladingo is saying they were a USL team, just that they only seem to be interested in fielding one going forward.
I agree that the league is not likely to give a shit any time soon, but this roster as it stands right now is certainly borderline, and no one is getting a good vibe about how it's going to look next season.
