Philadelphia ? Donovan McNabb smiled when a reporter asked for his opinion on the upcoming opponent and pumped his fist when the next question was about his poor start.

Once the topic switched to McNabb’s comment about black quarterbacks, his mood changed quickly.

In a bizarre interview that ended with McNabb walking off the podium at the Philadelphia Eagles practice facility Wednesday, the five-time Pro Bowl quarterback reiterated his statement on HBO that black QBs face greater scrutiny than their white counterparts.

“It’s just reality,” McNabb said. “It’s something that I’ve been a part of and other quarterbacks before and after me have been a part of. Did I expect any backlash? Yeah. Everything I say, I expect backlash from it.”

McNabb displayed a variety of emotions while getting peppered with questions on the race issue. He was perplexed and defensive – and looked more uncomfortable than he does standing in the pocket on his surgically repaired knee under a heavy rush.

“People are trying to dig too deep in this whole situation,” he said. “I wasn’t pinpointing particular people. What I said was the fact that we (black QBs) have to do a little extra. No matter the style of play you’re displaying, there’s always going to be criticism.”

Asked if any quarterback was criticized more than Chicago’s Rex Grossman last year, McNabb said: “I wouldn’t know.”

He then mentioned Peyton Manning, Carson Palmer, Tom Brady, Hall of Famer Steve Young and Jake Plummer.

“I never said Peyton doesn’t get criticized. I never said Carson doesn’t get criticized. I never said Tom doesn’t get criticized, because they do,” McNabb said. “They talked about Peyton not winning the big game. They talked about Tom Brady and his baby and girlfriend. We get criticized a little differently.”

Pressed for specific examples, McNabb pointed to being a running quarterback.

“Nobody ever talked to Steve Young about the running quarterback situation and Jake Plummer,” he said.

McNabb always has been sensitive about being labeled a running quarterback. He considers himself someone who passes first and runs only out of necessity.

“You wouldn’t ask somebody else the questions we get asked,” McNabb said, declining to reveal those questions.

The 30-year-old McNabb is in his ninth season with the Eagles after being selected with the No. 2 pick in the 1999 draft. He’s one of six black starting quarterbacks in the NFL. The others are David Garrard of Jacksonville, Vince Young of Tennessee, Steve McNair of Baltimore, Jason Campbell of Washington and Tarvaris Jackson of Minnesota.

“Black or white quarterbacks, we all go through something because that’s the life of a quarterback,” Vince Young said Wednesday after Titans practice. “You’ve got to be able to handle all the pressure. You’ve got to be able to handle the losses. You’ve got to be able to handle the media. If you can’t handle it, you’ve got to get off that position and go play something else.”

Young is the third black quarterback to start for the Titans franchise. The team won a bidding war to sign Warren Moon to a contract in 1984, drafted Steve McNair with the third pick overall in 1995 and selected Young in the same place in 2006.
