Who knows, but the options are:
Kansas City, Oakland, San Diego, Houston, Indianapolis, Atlanta, Carolina, New England
I don't know if they would put the Den/KC game in week 1 because it's not a "big crowd drawing game" to kick off the season when you look at fan interest.
Houston -- that's a dark horse, if for no other reason than they are going to be projected to do great things. You have Kubes as their former coach that just won the SB against their new QB, Brock. That could have some appeal and story lines, but I just don't see it as the viewership as a whole would have a greater "don't care" factor than Den/KC.
Patriots -- the obvious 'big draw' because of the amount of love/hate that the Pats generate and it would be the AFC Title game rematch, again in Denver. There's no Brady/Peyton storyline... but, it's a great ratings option and would likely be billed as Brady vs Miller.
Panthers -- the SB was on a neutral field and the Panthers took a big loss. Would this carry more ad dollars than New England? I think it's rare (would have to look) that the two teams playing in the SB face each other the next season. Not uncommon, but rare in the sense that the SB winning team would host the team they beat the following season.
If I were to wager a guess... I think it would be the Panthers, with the NFL hoping that the Panthers can 'rebound' by beating Denver in Denver and setting the tone for a new story line in 2016 that the Panthers are reborn and on a new mission to put 2015 behind them. And, for the 'tinfoil hat' crowd, this would be Denver's price to pay for being handed a SB ... getting smacked at home against the team you just beat for the title.
I think Carolina is the lead horse here, followed by New England.
