How the Races Were Won in 1991

by Sean Wrona

Just because I compiled this column a day after the previous one doesn't mean I'm going to do so every day but I had the time to do so this weekend. I was unable to find any good video footage or online reporting or sufficient information from the Greg Fielden books I own with regard to whether Davey Allison passed Hut Stricklin on the track or during a green-flag pit stop exchange, and neither would surprise me. I will probably generally refrain from making many overall comments until the series is over, but I'll say already that even at this point there are some drivers whose ratios of natural wins to total wins surprise me.
