Greatest players in each sport. Twenty seconds to think. Ready set go.

Odds are many of you named Ruth in baseball, Michael Jordan in basketball, Jim Brown in football, Gretzky in hockey, Pele in soccer, Tiger Woods in golf, Pete Sampras and Martina Navratilova in tennis, and Dale Earhardt in NASCAR. OK, throw in Secretariat in horse racing with Willie Shoemaker along for the ride.

Miss anyone?

Most of it is conventional wisdom which changes over time. But is it right? And if these guys are number one, who is number two? And who on that list makes a good claim at possibly being the best?

Baseball. Barry Bonds wrote himself out of this spot. Who can say what he's guilty of? Who can say what he isn't? Ty Cobb? Madison Avenue hasn't invented the PR firm which could reform his image. Not much power, either. Don't talk to me about Alex Rodriquez. We don't have that much time. Ted Williams? Not a complete player. Hank Aaron? Wagner, or a man who might well be the best ever, Nap Lajoie?

So, who's in second? I'll take Christy Mathewson. Before Ruth came along, Mathewson made New York fall in love with baseball. Mathewson set all kinds of records, but more than that gave baseball respectability with the upper class (and the chattering class-the media). Quite possibly the best pitcher of all-time, a master of control who never stood taller than in the spotlight of the biggest games. Erudite, largely a cipher, and the coolest customer of them all

Football. People get sentimental about Unitas, and he was the first great TV quarterback. But not as good as Elway. Jerry Rice is Cal Ripken. Joe Montana the definition of a professional. Lawrence Taylor a force of nature. Maybe Manning or Brady? Before it's over that argument will be made for one or both.

I'll go with Dick Butkus. Taylor had more talent, but Butkus was football. If you ever get a chance to watch one of his games on video, keep an eye and an ear open. Hard to describe, but a Butkus tackle sounded like a car wreck. Forward momentum ceased. Strong men flinched. Butkus and Brown had the hearts of lions.

All that aside, it always bugs me that Terry Bradshaw's name isn't higher on these lists. The man worked hard to harness enormous talents and won Super Bowls. The Steelers without Bradshaw would not have been any where near successful. Put aside the laughing image. This was a great, great quarterback.

Basketball. Russell for all the banners in the old Boston Garden, Chamberlin for how he changed the game. Jabbar for the sustained excellence. Bird and Johnson, linked forever in time as competitors and showmen. All were great.

I'd throw two other names in, along with a qualification. I don't believe Jordan was the best. Maybe not even in the top three. I've seen Julius Erving play and Doctor J. would eat Jordan's lunch. Heresy aside, the best all-around player the game has seen may be Oscar Robertson. He had it all. Scorer, tremendous assist man, solid rebounder, tenacious defender. If not the best, then certainly no slouch at #2.

Hockey. Gordie Howe and Bobby Hull were tremendous scorers. Rocket Richard maybe the most glamorous player ever. Too many goalies to name.

This is easy, though. It has to be Bobby Orr at #2, maybe even #1. The pure excitement of Orr rushing out of the Boston zone into open ice is perhaps unmatched in sports. Fifteen thousand people catching their breath at one time. Pure magic. Skills rivaling Gretzky's from a defenseman. Hard to explain to anyone brought up on today's game. There may be another Gretzky. There will never be another Bobby Orr.

Soccer. A subject I know little to nothing about. I don't put Beckham in Pele's league, however, and someone who knows more history might even suggest two or three better. Pele dominated his sport in the way Ruth did baseball for a time.

Golf. Palmer or Nicklaus. Toss a coin. I'd take Nicklaus on talent. If they somehow could be matched in their prime I'm not sure Nicklaus wouldn't have beaten him if the played just once. Over a stretch Woods is better, but he never had other great players to press him the way Nicklaus did.

Tennis. I suppose you're supposed to say Rod Laver, who may have been the best. I'd go with Bjorn Borg. And if I had to have someone go out and win one match, not sure that Jimmy Conners wouldn't find a way to win. The women's side of the coin is much clearer. If not Navaratilova then Evert.

NASCAR. I think we forget RIchard Petty all too easily. Behind the image of a good natured man in retirement is a record of unparalleled excellence. Earnhardt had the advantage of being around when the rest of the country discovered stock car racing. Petty was there at the beginning of the climb and won on guts and smarts.

Horse Racing. Secretariat may not be the greatest horse of all time, but he had the greatest film clip, pulling away from the field by what seemed like miles. Man of War, though, could easily be the best. What I wouldn't give to have seen them race.

Jockeys? I'll put one name in. Pat Day. Here it may be sentiment on my part, having seen Day ride and admiring his work for years. He perfected what is simply known as "the Pat Day ride", always knowing exactly when to make his move. Was he the best? I don't know, but he's the best I ever saw.

Number two is not a bad place to be. We don't remember number two, but we can always argue number one. It part of what makes sports so much fun.
