I wouldn't read much into the pace of the game. English football is uniquely fast - the Championship is the second-fastest league in the world but far from the second best. In terms of style and standard, the best teams in MLS would be comparable to teams in the bottom half of the Bundesliga and rest between B2 and B3. If you're talking about the pace of individuals players, I'd agree with you - MLS defenders are unreasonably slow, but midfielders and attackers are generally quite quick. I didn't see the game but from watching MLS in general and particular last year's finals, it would be similar to a bog-standard match in Germany.
