I share your regret we won't see Best 11s against each other, but any sense of asterisk-ness will dissipate almost immediately afterwards. Lots of major sporting contests have been decided or affected by injuries, flukes, bad calls, etc. Nobody cares (and probably rightly so).
Last year every sport went thru some sort of Frankenstein bastard format to get a champion, and nobody cares.
Especially considering that NYCFC will be without Taty, Parks, and Tinnerholm.
I guess I should clarify that the asterisk would be more of an informal "neither team was at full strength" kind of thing.
but you're both right, no one really cares in the end. in my mind, it just sucks we won't get to see a full on battle of two good teams.
this game will also be broadcast nationally on ABC... having both teams at full strength with an exciting game of quality soccer would have probably helped bring some eyes to MLS.
