Cards Kolb doesn't want to talk about Manning

Cardianls quarterback Kevin Kolb is declining to answer questions about the team's pursuit of Peyton Manning and more updates inside.

--Strong safety Adrian Wilson is donating $100,000 to Phoenix Children's Hospital. Medical care for children has been one of Wilson's favorite charities. Wilson's son, born several years ago, spent his first two months in a hospital.

--The average age of the Cardinals' opening-day roster likely will be skewed. That's because all three specialists have re-signed. It's a veteran group, to say the least. Kicker Jay Feely turns 36 in May. Long snapper Mike Leach is 35, and punter Dave Zastudil is 33. All performed well last season, although Zastudil has been hampered by injuries in recent seasons.

--Quarterbacks coach John McNulty attended the recent Pro Day of Arizona State quarterback Brock Osweiler. The Cardinals aren't likely to draft a quarterback, but McNulty is impressed with Osweiler, who left school a year early.

"Everybody talks about his height (6-7), but he obviously moves very well for his size. And that idea that he could have gone to Gonzaga to play basketball is something people take into consideration, for his athletic ability," McNulty said. He's showed a big arm today, that's for sure. He threw a lot of deep balls, which was nice."

--Quarterback Kevin Kolb is declining to answer questions about the team's pursuit of Peyton Manning for a few more weeks. Kolb politely said he would meet with reporters when the offseason program begins on April 16.
