Vince Spadea is apparently in demand to coach. Players respect Spadea's sucessful 15 year ATP career, some big wins, good success in majors, with a pretty basic vanilla game. Bogomolov recently asked Vince to coach him but Vince declined. Spadea wants to coach Young who he thinks can be #1 in the world. Spadea also would like to try to coach Gulbis but thinks Gulbis might not be a good listener.
The info is in this article, for those who don't believe...
Good to see Spadea breeaking back into the game, he's a real character and his book "Break Point" was/is a cult classic.
