I'm not sure whom you are speaking of but it certainly wasn't me. Are we playing better? Absolutely. But we're still a .500 ball club right now facing a team that has historically had our number. We've never beaten Andrew Luck. We've never won at Lucas Oil. 10 straight losses. And back in week 7, the Colts beat the Titans with only Hilton and Doyle to throw to. (yes, I know, saying "only" Hilton doesn't give him his due).
The problems of the last game were an inability of the offense to maintain drives early on, resulting in field goals. We never led in that game. For a team that allowed Luck to be a pinata for much of the season, Indy's O-line all of a sudden looked a lot more stout. We failed to get the the QB and to make adjustments when we weren't succeeding.
Mariota didn't have a terrible game but it wasn't a great one. He put two footballs on the ground, losing one and we can't have that and win against a team like Indy. Murray had a good statistical running game but Henry was barely used.
We have to start fast like we've done in recent weeks. We hung three TD's on Green Bay before they had an answer and then we hung two more before the end of the first half. We can't afford to turn the ball over. And the defense has to step up and do better, both on the line (which was a surprise in the last game) and the secondary (which wasn't).
