"HAVE SOME fun. That's all John Brenkus wants you to do with the quarterback analysis he presents as part of his latest "Sport Science" segment on ESPN tonight.

Have some fun with it, use it as pregame trivia and in-game filler. Test your friends. Test your memory with it.

But please . . . don't use it as further evidence that Donovan McNabb could never win a Super Bowl.

Even if that's what his offbeat science suggests.

"I'm not saying trade McNabb," said the host of the three-time Emmy-award-winning show. "Look, John Elway won the Super Bowl and he was 38. He was the oldest ever.

"But he was the exception to the rule."

Well, one of the rules anyway. Elway's jaw, height, weight and home state gave him a decided edge the two times he won the Super Bowl.

The 30-minute show, airing at 7 tonight, also compares the difference between circus catches and textbook ones, measures the power of a running back against a diesel engine, and puts you in the shoes of an NFL referee about to be hit. Brenkus, the creative director and co-CEO of a company called BASE, has made a nice career looking at competitive sports through an alternative prism, often with intriguing findings.

Like the one about home states.

"Every one of the Super Bowl-winning quarterbacks comes from 13 states and one Canadian province," Brenkus said. "Louisiana has produced seven Super Bowl-winning quarterbacks. The state of California has produced nine."

Elway is from California. Peyton Manning is from Louisiana.

McNabb is from Illinois. He would have been the first winning Super Bowl quarterback from that state had he not . . .

Oh, never mind.

If you don't know, four Pennsylvania quarterbacks have combined for seven Super Bowl victories. Joe Montana has four, Johnny Unitas (who teammed with Earl Morrall) and Joe Namath each won one.

And everyone knows who the other guy is, right?

Jeff Hostetler, pride of Holsopple, in Super Bowl XXV.

Drew Brees? He's from Texas. No state has sent more players into the NFL than Texas, more than 2,000 in all. But . . .

"Not one winning Super Bowl quarterback," Brenkus noted.

Only one Texas-born quarterback has even appeared.

Patriots quarterback Steve Grogan, from San Antonio, replaced Tony Eason in the second quarter of Super Bowl XX, won by the Chicago Bears, 46-10."
