Do You Think This Is Blocking? (Video)

Saturday night’s Coke Zero Sugar 400 at Daytona was full of carnage and mayhem. One of the big crashes took out at least 20 cars. In this crash, Brad Keselowski blamed the lead car for blocking his pass, causing him to have to slow down and consequently getting run into from behind. Keselowski vowed to wreck any cars who attempt to block him in the future. What do you think? Do you think the leader blocked, causing the multi-car pileup? Video c/o NASCAR on Youtube.
