I don't usually comment here because I don't follow the NFL like I follow CFB but I am a Browns Fan at heart and this season feels so much better than those of the recent past but at the same time it feels like it has already turned into a "what could have been" situation.
Here are the Browns' 16 opponents this year sorted by their current records:

I don't know if this is still true but I heard not long ago that the Browns had played the toughest schedule to-date in the NFL. That wouldn't surprise me. They have played four games against teams that are 7-2 or better (1-3) and a total of eight games against teams that are at least .500 (3-5).
I feel like the losses to the 49ers, the Patriots, and the Seahawks are understandable especially since at least the last two were reasonably competitive. The win over the Ravens looks like an anomaly now, but it is a REALLY solid win. Overall, being 3-5 against teams that are .500 or better really isn't bad. The loss that really stings is that loss to Denver.
The Browns are still mathematically in the hunt and they are 2-0 in the division which could make a big difference as the first two tiebreakers are H2H and divisional record if they end up in a tie for the Division but the problem is that getting into a tie with Baltimore seems pretty far fetched right now. The Browns trail the Ravens by 3.5 games with only 6/7 to go so in addition to the Browns playing extremely well down the stretch, they would need the Ravens to do no better than 3-4.
The Browns have six games to go:
- Four are games they certainly should win against bad teams (Cincy twice, Miami, Zona)
- One is a rematch in Pittsburgh against a .500 team that the Browns beat the first time
- One is a rematch in Cleveland against a 7-2 Baltimore team that the Browns shredded on the road
It isn't crazy to think that they could finish at least 4-2 but that only gets them to 8-8 and that will not be enough to get to January. Realistically they will almost certainly have to finish at least 5-1 and I haven't seen enough consistency out of this team to make me think that they can.
