There's an expectation from fans that a ticket to Bristol Motor Speedway will get them a seat to NASCAR's version of the Roman Colosseum.

They got one of those throwback, rock 'em, sock 'em races last August, when changes to the track surface forced drivers to get aggressive again and caused tempers to flare.

Now, a month into a new Sprint Cup season, NASCAR could use another race like that one.

Sunday's race will be the fourth for the new Gen-6 car, and the first this season on a short track. It could be the spark NASCAR needs at a time people seem to be holding their breath.

Only this week, nobody knows what to expect at a track once beloved for its action-packed racing and drama it produced.
