In Kansas City, Mo., two striking National Football League players waved rifles and yelled, "Where's the scabs." In Houston, picketing players pelted a bus carrying non-union players with eggs. And in New York, the Giants walked the picket line singing, "Momma, Don't Let Your Babies Grow Up to Be Scabbies."

Day Two of the NFL Players Association strike saw the vast majority of players turn out in support of the union yesterday, joined in most cases by members of other labor unions.

Still, several players did cross picket lines, including two of the biggest names in the NFL: Randy White of the Dallas Cowboys and Mark Gastineau of the New York Jets. And some of the players who did observe the strike said they might return to work and join the replacement players if the Management Council and Players Association, who resumed negotiations yesterday in Philadelphia, cannot reach an agreement soon.

Perhaps the most bizarre scene of the day occurred in Kansas City, where veterans Dino Hackett and Paul Coffman arrived in the back of a pickup truck carrying rifles. "We want to know where the scabs are," they hollered to their teammates. "We're going rabbit hunting," said nose tackle Bill Maas, who was driving the pickup.

But Hackett later said the rifles were not loaded, and "we just wanted to keep this as light-hearted as possible . . . "

None of the non-striking players aboard the chartered bus in Houston were injured. At least one rock was hurled toward the bus and one incoming replacement player dodged an egg as he entered the practice facility.

There were no such incidents reported in Cincinnati, but Bengals quarterback Boomer Esiason -- his club's union representative -- said, "Right now tempers are real high. There are possibilities of real violence. If we had been up here when the replacement players arrived, there could have been some."

About half the 28 NFL teams brought replacement players into their camps yesterday, with the others preparing to bring players in today as clubs prepare to play on Oct. 4 if the players association continues to strike.

Several of the replacement players were college stars or players who once played in the NFL or now-defunct U.S. Football League. Vince Evans, once a starting quarterback with the Chicago Bears, explained his signing with the Los Angeles Raiders by saying, "I've exhausted every opportunity to get back into the NFL . . . this is a chance to fulfill a dream."

In Denver, Broncos player representative Ricky Hunley didn't have much sympathy for the strike breakers. "Those guys were in training camp with us and we helped them . . . Now they're coming in and taking our job. I don't have any respect for them."

Quarterback Mike Hohensee, who played for the USFL's Washington Federals, apparently has signed with the Bears. And the Cowboys signed several easily recognizable players, including kicker Luis Zendejas, quarterback Kevin Sweeny from Fresno State (the last player cut by Dallas in preseason), former Maryland back Alvin Blount and Tennessee all-America linebacker Dale Jones.

But it was White, the former all-pro and former Maryland all-America, who made the biggest splash of the day in Dallas, when he rolled his truck through the picket line in Valley Ranch. "He holds himself out as a regular working-class guy, he perpetuates this image and then he does this," teammate Jeff Rohrer said. "It's gonna have some impact on the defense when we get back on the field together."

It led union rep and tight end Doug Cosbie to the point of wishing he was striking with the Washington Redskins. "When you think of the Redskins, you think of solidarity," he said. "They stood together as a team during the strike in 1982 and they came out of it strong enough to win the Super Bowl. We've got to build that kind of solidarity here."

After lunch, most of the striking Cowboys drove across town to a field behind former receiver Drew Pearson's sports shop, where they held an impromptu practice. Cosbie said they are trying to work out arrangements to practice at Southern Methodist University if the strike goes on much longer. When it was suggested that maybe the Cowboys ought to play in the place of SMU this year, since the Mustangs had to drop their schedule after getting caught cheating again, Cosbie said: "Yeah, and if we played as SMU, we'd probably get paid more, too."

There was little joking in Hempstead, N.Y., where defensive end Gastineau said that crossing the picket line "is the toughest thing I've ever gone through in my life. I'm being loyal to the people who have been paying me for nine years {owner Leon Hess}. I've had people not talk to me on this team and I've gone through a lot and I will go through more. {But} Mr. Hess has never not talked to me."

In Tampa, Buccaneers Coach Ray Perkins was less than enthused about coaching a group of replacement players he called "Team B." Did Perkins think he could get a team ready to play by Oct. 4? "None of them are in shape to play," he said. "A few of them are in poor shape and we've got a couple that are in no shape at all, not even poor."

John Reaves, a former NFL quarterback, who has signed to play with Tampa Bay's replacement team, was thankful the Buccaneers were one of the teams that chose not to picket. "It's ridiculous for grown men to be threatening people and acting like criminals," he said.

Another Tampa replacement player, 30-year-old defensive end James Ramey, was blunt as to why he is coming out of retirement and leaving his job as an insurance salesman. "Because I have a chance to make two months of pay in one week," he said.

Cornerback Elvis Patterson (who got burned so often by opposing receivers his nickname was "Toast"), cut by the New York Giants nine days ago, signed with San Diego. The Chargers also signed Calvin Muhammad, a former Redskins and Raiders receiver.

Billy Ray Smith was one of the San Diego players who picketed, but said he refused to get upset about the replacement players "taking my job" and compared the situation to an actor worrying about his understudy. "If Richard Burton got sick the night before playing Macbeth {on Broadway}, he wouldn't be worried if Pee Wee Herman replaced him for a day," Smith said.

Jim Zorn, a former Seattle Seahawks quarterback who had decided earlier in the week he would cross the picket line and play for his former team, changed his mind after criticism from his old teammates mounted. Zorn had been in Buffalo for a tryout but instead decided to sign on as a replacement player with Seattle, where he had been from 1976 to 1984. But after talking with Seattle union representative Kenny Easley, Zorn said he would not cross the picket line.

In Foxboro, Mass., Patriots player representative Lin Dawson said the team feels loyal to the Sullivan family, which owns the New England team. But Brian Holloway, who was involved in a controversial trade from the Patriots to the Raiders -- the NFLPA says because of his union involvement -- was there to urge his former teammates to stay with the union, "because this is not an issue of loyalty, it's an issue of players' rights."

Striking New Orleans Saints players wound up in a shouting match with fans last night in a hotel lobby. One elderly man threatened to burn his season tickets, and safety Dave Waymer replied by handing the man a book of matches. When 45-year-old Larry Lott came to the elderly man's defense, he wound up confronting a dozen or so players. After what was described as a vulgar exchange with receiver Lozell Hill, a Saints official restrained Lott and led him away.

Fans in Orchard Park, N.Y., the Buffalo Bills headquarters, didn't care for either side. One sign read: "NFL Again Bites the Hand That Feeds Them." Special correspondents Matt Lait in Los Angeles, John Pope in New Orleans, Susan Kelleher in Denver and Michael Rezendes in Foxboro, Mass., contributed to this report.
