Don't let your fan bias blind you
Did you see what Sproles did to the Bears defense? I bring up Sproles because he has a similar skill-set to Best and I expect Detroit to use Best in a similar fashion.
The Bears can be run on; Turner, Grant and Williams have all proved that, Best isn't much of a runner but if your in a PPR league Detroit will use him in the receiving game quite often, which is what I expect to happen. Not to mention Best put up solid fantasy points vs. the Bears last year.
I like Starks if Grant does not play but all indications are that Grant will indeed play, which limits Starks value.
