Yes, and I'm tired of pretending he couldn't. Or however it is people say that quote.
Purdy played great, some brilliant execution on timing dependant throws. Once his oline got banged up he started to get a little too much heat. Chris Jones is a stud. Karlaftis is a stud (I really rated him coming outta college he's going to be a force, not as impactful immediately as others in his draft class, but he's a stud, you'll hear his name called as often as you used to hear JJ Watt.)
Mahomes was able to exploit the middle after greenlaw went down (heal up soon man best wishes on a speedy recovery) and I don't think shanahan did any favours switching up from his zone scheme to man. If it ain't broke don't fix it and it weren't broke. That 9ers D was an immovable object before they started tinkering with it. And the offense was just proficient enough to get some points if they'd kept doing what was working. Granted TDs were sparse but you can win games with FGs and an elite D.
Commiserations 9ers, and congratulations Chiefs.
