Some numbers I considered:
SF rushing game is not good.
The IND run defense is decent.
The IND rushing game is very good and is even better at home.
The SF rushing defense is just average.
SF - Y/A is 31st at 3.5 and PE/Play is 31st at -.032
IND - Y/A is 6th at 4.8 and PE/Play is 1st at .104
Away SF - Y/A is 31st at 3.3 and PE/Play is 31st at -.050
Home IND - Y/A is 1st at 5.5 and PE/Play is 1st at .158
SF Run Def - Y/A is 17th at 4.3 and PS/Play is 22nd at .301
IND Run Def - Y/A is 2nd at 3.7 and PS/Play is 24th at .291
Away SF Run Def - Y/A is 12th at 4.2 and PS/Play is 18th at .295
Home IND Run Def - Y/A is 15th at 4.3 and PS/Play is 23rd at .307
The issue is that SF has a decent passing game and IND does not with the QB situation.
The issue this year has been that SF cannot get pressure on the QB.
IND, on the other hand, will have Rivers getting rid of the ball very quickly with short passes behind setting up the run.
Away Pass Defense SF - Rating against is 29th at 107.8 and PS/Play is 29th at .268
Compared to 16th at home rating of 92.2 and 26th PS/Play at home of .154
Home Pass Defense IND - Rating against is 8th at 78.2 and PS/Play is 15th at .233
Compared to 16th away rating of 96.6 and PS/Play is 28th at .098
SF - Away Pressure% is 30th at 29.6%
Sack% is 31st at 3.6%
PS/Play is 26th at .077
IND - Home Pressure% is 19th at 38%
Sack% is 12th at 6.8%
PS/Play is 17th at .146
Since IND has had the injury at corner and is thin at that spot they have mostly been running Cover3.
This is one of the ares Purdy has struggled a bit.
Against Man coverage he has a rating of 121.9 and against Zone coverage he has a 78.2 rating.
But Purdy has been playing very well lately, period.
So, this IND defense will have to be able to get the pressure on him to see any advantage play out here.
