I actually thought about Woods, but then I remembered this...Woods stared in a show a couple years ago called "Shark". It debuted during the strike-shortened season, but had good ratings. When it came back, it still had good ratings for CBS and handily beat its competition (in fact, it had better ratings than any other drama on NBC at the time). And yet, when it came time to renew it for its third season, it was canceled.
You have to ask yourself, "Why would CBS cancel a successful show?"
I'm not sure it had such good ratings in the second season. CBS kept moving it around. It ended up on Sunday night, but I could never DVR it because during football season, the starting time of TV shows varies because football games tend to run over. I must have missed half of the second and last season.
If it did get good ratings, it may have been canceled because it may have appealed to the wrong demographic (people over 30). Networks tend to target young consumers now. CBS canceled Dr. Quinn for that reason.
