I think your defense is going to get owned, although I admit to being in the minority on this. The Pats are coming off a bye week, play at home, and they're facing Denver's offensive line, which just lost its starting center last week. Denver is among the riskiest D's to start in Week 8, IMHO, and I'd be checking the free agent pools for Jacksonville, Carolina, Cleveland, Arizona, etc.
Other than that, and with the change to Coles, I think you look good. I think Denver will kill you though. Denver has a great run defense, but in case you haven't noticed, NE doesn't run the ball much. Denver's Quarterback Rating Allowed is pretty bad (19th) and they are only ranked 16th in scoring defense. By comparison, Brady has the 8th highest QBR and the Pats are 9th in scoring offense. Denver is a poor choice against the pass happy Patriots. Defensively, there are only six or seven teams which have worse matchups for week 8.
