Low All Star odds on Favorites

Anyone have any idea's on why 5dimes has the worst odds on the favorites in the all the Nascar races this week? Usually they offer better odds than the others. I noticed last week they had better odds on most drivers after qualifying. I'm relatively new when it comes to watching line movement in Nascar and have a lot to learn. I would guess that there has been a lot of money being laid on Busch at that one book?

All Star Race:
Busch +350 - 5dimes (This is not the nationwide series!)
Busch +500 - Sportsbook
Busch +600 - TheGreek

Showdown:
Truex +150 - 5dimes
Truex +180 - Sportsbook
Truex +160 - TheGreek

Truck Series:
Busch +200 - 5dimes
Busch +250 - Sportsbook
Busch +250 - TheGreek

* All odds posted were before qualifying.

Are they playing around trying to see how many people they can get to jump on that line or do they know something we don't? Sure the JGR cars have dominated at this type of track this season and the race fits busch's aggressive driving style but +350 in a NSCS race? On a driver that has four DNF's in his seven All Star races? I would expect to see better odds on him after qualifying as long as he doesn't smoke everybody with his lap time. Would like to hear other opinions on the low odds this week at dimes...

 

dimes is usually the best odds in nascar but the past 3 or 4 races they haven't been!!! especially with the favorite n cup races ,kenseth and kyles lines... at times i feel they watch this forum  

I feel the same way stats   Dimes has the best odds but it doesnt take much to move them. Bet a 100 on a driver to win at 10-1 and the odds will usually drop at least to +950 within a couple minutes.  Bet max on a matchup which 250 for me on say a -120, it may go all the way to -150 within a few mins. Ive never been to a vegas sportsbook but i would say i could bet 1000 on the same and they wouldnt move it at all.
