Webb site: Alan Webb, who set the U.S. mile record in 2007 but has struggled since, announced in August he was leaving long-time coach Scott Raczko to join Salazar's group in Portland. He's also recovering from an Achilles injury.

"Things are going really well. He's been here three or four weeks," Salazar said. "He's running five miles a day. He feels his Achilles, which has been bothering him for nine months, up to 10 minutes at the start of the run. Then it goes away. I watch while he runs to make sure he's not pushing it."

After analyzing Webb's training logs from 2007, when he ran the 800 in 1:43.84 and the mile in 3:46.91, Salazar thinks Webb, 26, can be better than ever.

"I really think the guy is going to do unbelievable," Salazar said.

Does Salazar think Webb is a miler or a 5K runner?

"I don't know," the coach said. "I think for right now we're going to stick with the 1,500 and mile. I don't want to turn tail and give up (on the mile). Let's get him better than he's ever been at the mile and then say, 'What do we think?'"
