Don't really think 9-7 will make it though possible. For the purpose of this discussion I will eliminate this weekends game. It isn't that it is irrelevant, its that if they lose they clearly have to win the last two to get to 10 wins and would automatically be in on that scenario by virtue of having 3 of their 6 losses out of conference and hold a tie breaker against virtually everyone.
I think the major game comes the week after against KC. If they won that one they would have piled up a ton of tie breakers. The most dangerous teams being the Ravens who have an easy finishing schedule and the Chargers (Den/SF/ KC) who are in real tough to lose one more conference game and therefore losing all tie breakers. Obviously there are other teams like Buffalo and Miami, but they will almost certainly get to 7 losses (Buffalo plays GB this weekend and Miami has the Pats in NE). The Browns would have to create another playoff hole on the way by beating the Bengals and Ravens.
