Broncos-Chargers
I think it's funny how the narrative in the DEN-SD game for many people is how there's no way Peyton can lose to the Chargers again AND there's no way they can lose in the Div round again at home to a big underdog. No pressure though...
The patchwork SD defense is going to have a tougher time against Peyton than Dalton, but at the same time, Manning has always had a tough time with the San Diego defense. In his last 10 games against SD, Manning is only 4-6 with a 23-18 TD/INT ratio (Most of those INTs were generated by pressure at the LOS, rather than in coverage). Even with the large turnover in personnel, the constant in this equation is John Pagano, who you can expect to have a very well constructed defensive gameplan for SD. I think the Chargers will get to Manning a couple of times in key situations here to stall Bronco drives, and consistently put pressure on him to hurry his throw, which will minimize the deep balls and force Denver to march down the field instead of taking big bites. The key here will be to clamp down on those short passes, and not allow many YAC, as not one of these Bronco receivers goes down easily. It will be all about making Manning earn points with time off the clock and avoiding the quick score. SD's defensive stats are not overly impressive over the course of the season, but in the last 6 weeks, they've shown a marked improvement, moving them from one of the worst defenses to a fairly average one.
On offense, Rivers is looking to confident right now largely because he has an OL that's actually been effective in pass protection this season (8th in adj. sack rate). Keenan Allen in particular has been making huge plays for him downfield and Danny Woodhead has arguably been the best free agent signing of the year, serving as a good pass protector and great checkdown option to keep drives moving. All the SD tailbacks are solid in protection, which is a problem for Denver. Coming into this game, they're going to be without both Von Miller and Derek Wolfe, leaving only Shaun Philips as a capable pass rusher that could have an impact. I don't think Denver will be effective in getting pressure on Rivers very often in this game.
I think San Diego can absolutely win this game, but I'll play the +10. Ultimately, for SD, this game is going to come down to shortening the game as much as possible in preventing big plays from Manning and forcing them into longer drives to score, and in extending their own drives through leaning heavily on their running game. SD & DEN are the two best teams in the league in offensive drive efficiency (76.2% & 78.1% in drive success rate), but have drastically different pace stats. I want to see the Broncos limited to 10 offensive drives in this game.
Key Points for an SD Win:
1) Time of Possession. Beating Peyton starts with forcing the clock to keep rolling on both sides of the ball. Make him earn points with long drives by avoiding big plays. On offense, SD needs to do the same, converting 3rd downs and not being afraid to be aggressive on 4th and short once over the 50 yard line.
2) Penalties. Both Peyton and Rivers are among the leaders in the league in drawing DPIs. No net advantage. However, Denver was among the leaders in committing defensive penalties (54) this season, compared to San Diego (33). The Denver secondary has been known to make huge mistakes downfield, and I think they make at least 1-2 in this game if Rivers is aggressive.
3) Ball control -> Run the ball. Both for offensive gains and clock management, I want to see 40+ carries in this game for the Chargers. Ball control has seen them lose only one game by 10 or more points this season (17-27 to OAK) and it took a -5 TO margin for that to happen.
I think the +10 is very solid. No matter how good Manning and his offense is, this is a team that's given up a lot of points this year, Among playoff teams, only GB allowed more scoring against them, and at least the Packers can blame their offense's inability to sustain drives without Rodgers on the field. Denver has no excuse. Peyton's career also includes a 9-11 postseason record and 8 first round losses despite being on a 12+ win team in 10 of 14 seasons. So if you're still thinking there's no way Denver loses this game, you should probably reconsider.
