The pro football regular season is entering Week 12, but the top three spots in the latest Las Vegas Sports Consultants Power Rankings remain unchanged.  The defending champion New York Giants (144.6) retained their top spot according to LVSC over second-place Pittsburgh (143.4).  New York continues its winning ways by posting a 9-1 straight up and 8-2 against the spread record, and leads the most powerful division in football.

Now the Giants take on another division leader when they travel to Arizona to take on the Cardinals (139.8), and they are currently listed as a 3 1/2-point road 'chalk.'  Arizona has never had much of a homefield advantage, even since moving into its new stadium a couple of years ago.  This also marks New York's first trip back to University of Phoenix Stadium since last year when it won Super Bowl XLII against New England.

Tennessee (143.0) remains entrenched in the third spot despite being the lone unbeaten team in the league.  The Titans (10-0 SU, 9-1 ATS) continued their winning ways by upending Jacksonville last weekend as a three-point road favorite, 24-14.  Now the Titans host the red-hot New York Jets (7-3 SU, 6-4 ATS) who are themselves riding a four-game SU winning streak.  LVSC opened Tennessee as a 5 1/2-point 'chalk' after factoring in homefield advantage.

Here's a closer look at all the Week 12 power rankings.
