For me, it's mainly strength of schedule with a bit of winning margins thrown in.
Winning margins come in for me with mostly beating the teams they are ''supposed to beat'' the way they are supposed to beat them.
If a team is favored by 24 and they win by a touchdown, they may not be as strong as originally thought.
By the same token, if they're beating teams that should be able to beat them or at least play them close by double digits...that team may be better than originally thought or at least as good.

Works for me ...
