He was at best a borderline option based on his form, and his history with Klinsmann was clearly fatal.
As good as he's been, he's always been an epic head case. Turning down the offer to join Bayern seemed to signal to Klinsmann that Donovan lacked the ambition needed to be truly great. And this was hardly the first data point in that column.
I think there he's certainly more valuable than several of the players on the squad, but at the same time I can see Klinsmann putting a team on the field that wouldn't include him for footballing reasons alone.
I absolutely reject the idea of bringing him as a show pony or to deal with the media.
My biggest concern from within the camp is what this has done to undermine an already patchwork locker room. You have a few remaining vets, a bunch of new, mostly MLS-based faces and the Hessian dual-citizenship corp. I can see some pretty significant schisms developing if things go badly. I don't think Klinsmann has done himself any favors here by naming Dempsey as Captain. Bradley is clearly the real leader of this team and for all his other qualities, Clint just doesn't seem to command the respect of the team.
That said, a victory against Ghana would right a lot of ills. I don't think a result against Portugal is out of the realm of possibility. As great as Ronaldo is, the Portuguese have a way of being their own worst enemies. I can see Ronaldo being isolated from lack of service or having to track back to less dangerous territory to help his teammates deal with the US pressing game.
Nothing like leaving off the most recognizable face from a mediocre team, in a country that doesn't really care. He could just sit the bench and do all of the interviews. That at least would keep the team on the radar a bit in the states.
We'll see what the TV numbers look like, but I expect no significant impact from Donovan's absence. John Skipper at ESPN and the team at NBCSN have been incredible force multipliers for the burgeoning interest in soccer in this country. I think you'll see better ratings for the US games in the group stage than we saw in South Africa.
