OK, I am going to give you all the inside scoop on what went down at Darlington. I compiled this straight from various comments on the Blaney fan page so I know its factual.
NASCAR did not want Blaney to win this race. In two prior races NASCAR rigged his engine so it would blow up and also in two other races had drivers wreck him. Apparently Blaney is getting too much star power and is taking some of NASCAR's spotlight. So here is what went down. As soon as Blaney took the lead, they radio'd to Reddick to hit the wall, at the same time they had told Larson to pick it up and pass Bubba in the turn. Race control was already in the process of informing Bubba that he needed to take one for the team and should maintain his driving line and punt Larson to create a caution. NASCAR knew that Hamlin would then take the lead during the round of pit stops since they had informed him he could speed on pit road and they would not assess a penalty. Hamlin would then drive away from the field during the GWC as Bell and Byron would block for him. They had informed all drivers to not wreck because they network needed to wrap up coverage and get to a USFL game. NASCAR feels that giving Hamlin a win will put them in a better bargaining position in some lawsuit that apparently is going on.
I think I got most of what was reported. And just as an FYI, several posters shockingly stated they were done watching NASCAR and were leaving the fan page.
