Since the Patriots started the season 7-0, there has been a lot of talk about how great the Pats offensive line has played thus far. I agree. But no QB has enjoyed great offensive line play longer than the Colts Peyton Manning. His line has played at an unbelievable level for 5 years or so.
With the retirement of Tarik Glenn, Manning hasn't looked quite the same. He's got rookie Tony Ugoh playing left tackle, and Patriots fans know only too well what happens when a QB has an inexperienced left tackle. Let's just say, I'm glad Matt Light is healthy again.
Manning is still playing great, but the Colts offense is not nearly as explosive as it used to be. I am not saying that Glenn is the only reason for this, but he's one of the main ones.
