Passing thoughts: NASCAR drivers differ on blocking

MARTINSVILLE, Va. — Tony Stewart says never. Joey Logano says late in the race. Jimmie Johnson says to protect a victory in the final laps, except, perhaps, if Stewart is behind him because of the potential consequences.

Theories on blocking and when it is acceptable vary widely in the NASCAR garage.

The topic has become a hot one since the last race two weeks ago in California, where an infuriated Stewart confronted Logano’s crew and accused the young driver of blocking him late in the race.

‘‘I don’t like blocking. I never have, I never will,’’ Stewart said at Martinsville Speedway, site of Sunday’s STP Gas Booster 500. ‘‘It’s our jobs as drivers to go out there and try to pass people. That is what racing is about. We didn’t have blocking 10 years ago. I don’t know where all of a sudden some people think it’s all right to do now and think it’s common practice. I don’t believe it should be common practice.’’

Others disagree, especially when trying to win.

‘‘When you are in the sport long enough, you realize what those decisions could lead to and, honestly, who you throw a block on,’’ Johnson said.

‘‘They could come back and haunt you, so as we are trying to win a race, win for our team, win for our sponsors, there are these other elements . . . that flashes through your mind when you throw a block,’’ he continued, adding that if you see Stewart approaching in your rearview mirror, ‘‘you probably expect something is going to happen.’’

Blocking can be continually positioning your car in front of theirs, or taking away their preferred line around the track by adopting it for yourself, even if it’s not your preferred line. The thinking is if a driver is gaining on you, taking away his line can slow that.

At Martinsville, where the Sprint Cup Series will race 500 laps on Sunday, cars typically swing wide heading into the turns at each end of the track, then hug the inside curb. A blocking maneuver by a leader might cut down that wide swing, forcing a challenger to drive higher up in the turn away from the curb. It helps to know a fellow competitor’s views, and tendencies, he said.

‘‘He has made that known over the years, so there are guys you probably don’t want to do that to,’’ Johnson said of Stewart. ‘‘But then again, to defend for a win, you have to take some extreme measures at times.’’

Logano feels like he was taking those measures at Fontana, but wound up getting tangled up with Denny Hamlin, sending Hamlin into the wall, and Kyle Busch passed them both and claimed the victory.

Presented with the same circumstances Sunday, Logano would take into account where in the 500 laps they are, but at the end, said he’d race the same, and thinks Stewart would, too.

‘‘Late in the race, I would probably do the same thing if it’s the right move at the time, but early in the race I wouldn’t,’’ Logano said.

That position, Jeff Burton said, is valuable information, as is a driver’s history.

‘‘You have to remember what you do to somebody, you have to expect it’s going to be done back to you,’’ the veteran driver said.

It’s essentially about drivers policing themselves, he said, which can get complicated with a victory in the balance.

‘‘The problem we have in our sport is we have a lot of drivers that will complain when it happens to them, but when they do it to you they look at you like, ‘What’s wrong?’ ’’ he said.
