7. I've seen better races at this track.
From my perch in Turn 1, it looked like most of the passing was done either in the pits or within the first three laps of a restart. Kenseth, Johnson, Harvick, and Logano at various times mounted sustained charges through the field, but in Harvick and Johnson's cases that was because bonehead moves put them where they shouldn't have been in the first place.
Oh, and for the conspiracy theorists: I heard race control on the scanner discussing possible fluids from the #47 around lap 125, and later possible debris in 3 or 4. Neither resulted in a caution.
