Nascar and Danica...?

Ok I'm not up for the idea of NASCAR helping guys win races, but I do think they throw phantom cautions near the end to tighten the field again or get a top driver back on the lead lap or back in contention to win. Like at Talladega, NASCAR extended the caution for Ryan Newman's crash so it can go GWC and there will be less of a chance of Jimmie Johnson wrecking. That I know happens because I remember during the Busch race at Talladega in 2007 they threw a caution for a soda can down by the inside wall on the frontstretch. And this was while the field was starting to spread out a little bit. Do they do it to set up a good finish? Yes. Do they do it to get drivers back in contention? Yes. Do they do it so a driver can win? I highly doubt it.
