The Packers didn't have the talent to match up with the 49ers but what I believe played an even bigger role in them getting blown out was the fact that Matt LaFleur coached under Shanahan and that familiarity made it easy to stop them offensively.
I think the Chiefs will need to test Richard Sherman. We all saw DeVante Adams beat him last night on that 65 yard bomb. With Tyreke Hill speed and Mahomes scrambling ability and arm talent.... it will be a long night for Sherman. Hopefully the refs don't let them mug the Chiefs receivers and tight end. Which they tend to do in the Super Bowl. By the way, I think official for the Super Bowl is Bill Vinovich? That ref seems to let the defense play aggressive which is not good news for Chiefs.
