SAN FRANCISCO (KCBS) – John Madden called the KCBS morning crew from Chicago Wednesday before heading to the Hall of Fame induction ceremonies.

On the list of NFL topics Madden mentioned was the danger of dehydration as teams hold training camp amid a heat wave in the East. Eagles defensive tackle Mike Patterson was taken to a hospital after collapsing at a training camp practice on Tuesday.

“The biggest problem is the big guys,” said Madden.

Madden said not enough is currently known about when players are getting into danger. The coach said that he has learned that some players take as long as two weeks to acclimate to the heat.

“Everyone says ‘preseason doesn’t mean anything, and we need less of it,'” said Madden, but the coach disagreed and said the players need the time to get ready for the season.

Madden also discussed the Raiders losing tight end Zach Miller to Seattle. Madden said the Pro Bowler was a security blanket for the quarterbacks over the last four years.

” He was the go-to guy,” said Madden. “I thought they had made some room…I was really surprised when Miller left.”

Madden also weighed in on Tony LaRussa losing his cool Tuesday night in Milwaukee over the lighting in the Brewers-Cardinals game.
