Betting Notes; Kyle Busch looked good in practice and qualified on the pole, but those time don't really mean much to me like they do at a regular race. Busch will likely be fast, but might get a little too excited and find himself in trouble like he always seems to in the All-Star races. If anything, Busch might be a driver I look to bet against in match-ups with any of the 10 listed drivers above.

I would expect Martin Truex Jr to make to the All-Star race and contend for the win. The three drivers I think he'll be battling with are Greg Biffle, Matt Kenseth and Carl Edwards. And of course, you can't forget two-time All-Star race winner Jimmie Johnson.

I will also take a shot with Mark Martin who will be making his All-Star race record 23rd start. His high odds warrant a look and for the same reasons I like Truex Jr, I like Martin: these Waltrip cars are fast every week..

I can't say I'd be surprised if any one of the possible 23 drivers won the race. There will definitely be a little more excitement during the segments because winning a segment puts the driver into great position to win the $1 million by starting in the first two rows of the final 10-lap dash.
