Here is the Bills vs. Redskins official betting preview. Washington is -4.5 at Bodog with a total of 34. Notes compiled by OffshoreInsiders.com

Washington’s right side of the OL is a concern. RT Jammal Brown is out, RG Artis Hicks is struggling making the transition from tackle.

New Redskins signal caller Donovan McNabb is struggling. He is expected to see 12-15 snaps. For the Skins, in addition to Brown, out are WR Malcolm Kelly, who had 25 receptions last year, WR Mike Furrey, who caught 23 passes in 2009, S Chris Horn, and QB Richard Bartel. S LeRon Landry is expected to play despite a toe injury.

The Redskins are running a complex West Coast offense under new head coach Mike Shanahan and son Kyle, the offensive coordinator. Likewise, new defensive coordinator ditched the successful 4-3 in favor of an aggressive 3-4.

Led by new QB Donovan McNabb, the first unit offense will take 15-18 snaps. McNabb has been shaky in camp grasping the new offense. Guys fighting for roster spots (not starting unit) on offense will get more playing time in their next game.

Backup QB Richard Bartel is doubtful for the Skins. With newly acquired John Beck not familiar with the playbook, Bears castoff Rex Grossman may play three quarters.

NFL oddsmakers note that Buffalo is minus three starters on the offensive line:  LT Demetrius Bell, RG Eric Wood, RT Cornell Green. Trent Edwards will start at QB for the Bills but Ryan Fitzpatrick is expected to see a lot of action. He’s been alternating the No. 2 spot with Brohm, who is expected to get the bulk of the action next Thursday.

Bills starters will likely play “numerous series”. Three young O-linemen will see a lot of time: Kyle Calloway, Jason Watkins, Nick Hennessey.

The Bills defense is adapting to a new 3-4 scheme. Two starters are out on D: Paul Posluszny and Chris Kelsay, both LBs.

Last year the starting unit had 15 possessions and zero touchdowns in the exhibition season.
