Odds are Donovan would have been in Wondo's role as a late game offensive sub. It is easy to say Donovan would have finished the play Wondo flubbed, but we did get that chance because Wondo scrapped for a couple 50-50 balls to get us possession, so I don't want to kill a guy who probably will have nightmares for a while.
Where Donovan clearly helps, though, even if you don't like him or think he's not good enough any more, is set pieces and crosses. We wasted a few corners and direct kicks late in regulation and in overtime. Bedoya had a soft corner, Bradley put one out of bounds and then hit another one too low (and you'd like him on the receiving end anyway with his size). Not sure it would have mattered with Belgium being pretty solid in the air. And he's taken pressure PKs before if it came to that.
But 32yo LD clearly doesn't dent the talent gap between us and Belgium and Germany, so his absence won't be one of my takeaways from this WC, even though I thought he needed to be there. Mostly I'll remember Howard, the Portugal finish, overachieving to get out of the group of death, and possibly Green's moment of magic as the moment our next great player showed us a flash of what was to come. Hope so on that last one.
