BALTIMORE, JULY 12 -- The Baltimore Orioles occasionally might disagree on who should play where, what players to bring up or send down and how to pitch to hitters. But they seem to be united on one thing at the all-star break:

No, Bo.

Many Orioles, though taking a wait-and-see attitude on whether Kansas City Royals outfielder Bo Jackson can mix a pro baseball and pro football career, have doubts initially.

Jackson said this weekend that he would like to try to play football for the Los Angeles Raiders "as a hobby" during the baseball offseason.

Jackson, who won the Heisman Trophy as college football's outstanding player for Auburn in 1985, was selected in the seventh round of this year's NFL draft by the Raiders. He was picked in the first round of the 1986 NFL draft by the Tampa Bay Buccaneers, but opted to play baseball for the Royals instead.

"Realistically, no. I don't think you can put that much energy into two sports at a professional level. He'll be a marked man in football," said Orioles center fielder Fred Lynn.

Lynn played college football for one season at the University of Southern California. Although some people might be talented enough, most end up having to pick one career, he said.

"Sooner or later, you have to make a decision," he said.

Lynn said he thought the Royals wise to go along with Jackson. "It's good that Kansas City is letting him do this early, to get it out of his system," he said.

Orioles Manager Cal Ripken Sr. wasn't making any predictions.

"I don't know any damn thing about football. I can kick it 75 yards but I don't know anything else about it," he said.

He did say that things might be different if Jackson were playing for him. "I don't know if I had him on my club in baseball whether or not I'd want him playing football in the winter as a hobby," Ripken said.

Orioles General Manager Hank Peters said his immediate reaction was that the two sports are "not compatible. It would be difficult to combine the two of them."

In addition, if Kansas City makes the playoffs and World Series, Peters said, Jackson would be even further behind in his football preparation. "He's got a lot to make up in a short period of time," Peters said.

One Oriole, however, said Jackson might be able to pull it off. "Everyone cut him down when he said he would play baseball," outfielder Ken Gerhart said. "They said he was stupid, he was a fool. If he really wants to do it, I think he has the talent to do it."

Third baseman Ray Knight said getting ready to play football may take more out of Jackson than playing.

"You get into professional athletics {and} it takes a tremendous amount of preparation to be a peak performer. I can't see how a man can perform at the top of his game when he has to expend so much energy in two different directions," Knight said.

The psychological pressures, plus not having time off, may also affect Jackson, Knight said. "When my season's over, because of the mental strain and grind, I need time to myself." Following the World Series last season, Knight said, he wasn't the same for about a month.

"You'd never have an escape mentally," he said.

Most Orioles doubt whether an athlete can handle both sports; but, they said, if anyone can, it's Jackson.

"As good as he is, he'll probably slide in and do real well," Lynn said. "But I don't know if he can make the commitment. You'd hate to see him get creamed by some big middle linebacker."

In Toronto, Rick Leach of the Blue Jays, a former two-sport college athlete who chose baseball over football, said: "To me, the Raiders are thinking of future things. They want to give him a taste of football, hoping maybe he'll break his baseball ties."

Leach, a star quarterback at Michigan, is a reserve outfielder/first baseman with the Blue Jays.

Jackson is "a great athlete, but to me, that's some kind of tough adjustment," Leach said. "Of course, it's different playing quarterback than running back. But you get hit so much. It's a very, very difficult adjustment.

"But if anybody can do it, Bo Jackson can. He's so tough and fast. Athletes like that come along only once in a great while. The only other athlete to compare to him since I've been around is {Detroit Tigers outfielder} Kirk Gibson.

"There's a difference in the psyche of the two sports. Baseball is an everyday sport . . . You can't get too high or too low. Football, you only have to get up once a week."
