eagles -7 over lions?

[Neuman101]

Is there something im not seeing here...It seems to me that eagles were -7 last week too and lost the game by 8...so then this week against an equally good team in detroit, they are -7 again?!? Washington and Detroit are very different teams, and even if one assumes washington is better, should the line really be this high...someone plz give me a reason not to bet detroit, bc i feel like im jumping on the bandwagon betting against them...
