LAS VEGAS -- The
Seattle Seahawks opened as Super Bowl favorites over the
New England Patriots, but the point spread was on the move Sunday night.
The Seahawks opened as 2.5-point favorites at multiple Las Vegas sports books, but the number was down to a pick 'em at the Westgate Superbook and the William Hill and Wynn sports books within an hour after opening. CG Technology was holding at Seattle minus-1. The MGM had the Patriots as 1-point favorites.

<cite>Joe Nicholson/USA TODAY Sports</cite>The Seahawks opened as 2.5 favorites for the 2015 Super Bowl against the Patriots, but that line was on the move with kickoff still two weeks away.
There will be two weeks' worth of bets to shape what will be a highly anticipated Super Bowl on Feb. 1, in Glendale, Arizona. The Super Bowl point spread has never kicked off at a pick 'em.
Seattle advanced to its second straight Super Bowl with a remarkable
28-22 comeback win over the
Green Bay Packers in overtime.
The Patriots had a much easier time, blowing out the
Indianapolis Colts 45-7 in the AFC Championship Game.
This will be the sixth Super Bowl appearance for the Patriots under coach Bill Belichick and quarterback
Tom Brady.
The MGM took a six-figure wager on New England minus-1 on Sunday night, according to vice president of race and sports Jay Rood.
