Something stood out to me at around 1.20, see for yourself after the jump

As you can see, he was playing Defense. Also, if you watched the whole video, you may have noticed players joking around and such. They didn't seem to be taking anything seriously at all. Overall, I think there is no need to worry about this performance (if some people are) and I have a sneaking suspicion that DA BEARS were not trying. If we see the Packers again in the NFC championship game, I see a big win for DA BEARS.
PS. Sorry if this should have been a fanshot.
