If there was one thing obvious tonight (beyond horrible 9er oline),
AWESOME Chief's secondary.
Virtually all 9er's catches were tightly covered.
We've been accustomed to seeing some wide open receivers throughout this season.
I'm not sure Kittle failed. I'd bet that film will reveal that he was blanketed all night. That, or serving as a fulltime blocker, rather than a receiver.
Oline was rated 22. Strikes me as generous. Apologies to Trent, tho he wasn't at his best tonight, penalties aside
Horrible Niner oline?
I dont know which game you were watching but it was probably the best unit they had on the field. Jones was often contained with a lone blocker all night. And when the Chiefs did get pressure? It was mostly when Spags went cover 0 as the Dline wasn't getting it done. SF also had plenty of handoffs/carries where oline created holes for McC pop off some off. They had more trouble in obvious run situations but the Chiefs stacked the box.
As to your point about the Chiefs...they arguably have the best back 7 in football when healthy. Bolton is a stud, Gay is very good, Chennal had a good year. The CB tandem of McDuffie and Sneed is one of the best in the NFL. The safeties aren't quite as good but they are at least average.
In some of their packages, if/when utilizing more DBs, their depth is suspect. I wouldnt be surpiseed if Williams (#2) wasn't the worst player (statically) in the game. When in he was either picked on, missed tackles, or blew assignments.
I thought the 49ers won the line of scrimmage on both sides of the ball. The difference for me were the 49er skill players, an area they had a clear advantage talent wise, didn't produce. Samuel and Kittle were non factors (Chiefs D had something to do with that).
