My neighbor Stan, who has watched NASCAR since the 60's and raced himself, believes Hamlin allowed Stewart to pass him on the final turn at Sonoma. He says Hamlin drove in off-line, leaving the apex unprotected, and was not wheel hopping, as both Stewart and Hamlin had their rear wheels rolling in the video. Hamlin did lock his front brakes at one point. Stan think about 20% of the fan base agrees that the pass was staged.
In one way, it's a smart and good thing to have Tony in the chase, where he will undoubtedly wreck a few cars and create excitement for the fans and revenue for the tracks. So I won't complain too loudly.
