US Davis Cup team roster change?

So, first the news/speculation:

"Certainly Roddick and the Bryans, unless anything major happens in the next month, are essentially locks for the team," McEnroe said. "James certainly made a major statement in La Jolla. I wouldn't say that that's a lock, but ... I've spoken to Andre Agassi a couple of times and under the right circumstances I think he would be interested in coming back."

Am I the only one who thinks this choice is a bit insane? Let's see - we have a young guy who has done well for us in the Davis Cup, who has improved his ranking, and who has been healthy. And then we have an older guy who has been injured since late 2005 and has not played much...who should play?

I normally like McEnroe's coaching of the Davis Cup Team. You see him out watching the players, and making smart choices. Except for now - he should not even be considering this unless the grass surface is a major disadvantage for Blake.
