They’re going to be OK. That’s the word on the 13 Iowa football players who had to be hospitalized after workouts last week.

But as the diagnosis emerged — exertional rhabdomyolysis — the questions lingered: How did it happen? And why?

It’s what everyone wonders. Jim Radcliffe included.

“I want to know exactly what they were doing,” Oregon’s strength and conditioning coach says.

Right now, so do we all.

The soft-tissue ailment is caused by overexertion and can lead to kidney failure and even death in extreme cases. And its outbreak in Iowa reminds us of last August, and the McMinnville High School football team.

Remember? Two dozen players were diagnosed with some degree of rhabdomyolysis after an intense set of workouts during a preseason camp.

Radcliffe was reminded that in 26 years at Oregon he’s never seen a case.

And right about now seems like a good time to be glad Oregon has Radcliffe, whose methods are sometimes unorthodox but have produced very positive results.
