An interesting spread.
The spread being so high would seem to indicate that the Bears are resting starters, but does it really? And is that info really knowable at this point? Most reports seem to say starters will play.
Bears could be playing for a 1 seed, and you would think they would prepare in a manner that assumes so. They will not rest their decision to play starters or not on whether ATL and NO win; they will be committed one way or the other. Lovie also always puts beating the Packers as a top priority, as they are rivals.
Just thinking about the most probable case that the starters play, the value would appear to be on the Bears, cause you would think it would be about 3 if that were the case, but you still have to think Vegas wouldn't throw out such a high spread without good reason.
Maybe where they figure with the spread being so high is that the Packers will jump out strong early, get a significant lead at half, and THEN the Bears throw in back-ups for 2nd half, while Packers continue to pour it on full force in a must win for the playoffs. IF this happens, then -10 is a joke and the Packers win by 21+.
Either way, the Bears probably won't be motivated, while the Packers will have everything to play for.
The +10 might be a "trap" with people jumping on it for intuitively thinking it to be too high.
