Sounders utilize GPS devices for success on the pitch
TUKWILA -- It's a routine most of these guys could do in their sleep, suiting up for training and heading out the door. But now Sounders players are adding one more layer. It's an elastic band wrapped around their chests and it has become an essential part of the squad's training. "It's too different units, a GPS one and a heart rate monitor together," said Sounders head training coach David Tenney, who is responsible for the gear.
