Toronto FC's Jim Brennan, that is.
What's interesting is that Brennan is passing up on the regional championship of his country. In fact, Canada is the only team other than the U.S. and Mexico to have ever won a Gold Cup.
Brennan captains FC, though, and he thought that was more important.
Landon Donovan captains the Galaxy, but honestly, I think he'll be made to go to the Copa America.
I'll explain and give more info on why I believe this later.
Here's a hint - Donovan's skill is actually working against him here. If he was a nice, solid contributor, like Brennan, he'd probably be allowed to stay with his team, especially given the Galaxy's rather horrific injury situation right now.
But Donovan is better than that.
He's a real difference-maker, and so his wishes and his club be hanged - he's going to Copa.
