As I mentioned earlier in the thread, Stefon Diggs unexpectedly missing the game with a lingering injury seemed to ruin it for Thielen. Both were over 900 yards going into the game and the hype all week was about both of them going over 1,000 as the Vikings haven't had a thousand yard receiver in some time.
It was a meaningless game for Minnesota and they were well ahead of Chicago the whole game. Sam Bradford was completing passes with ease all over the field. Normally in these types of games, a great deal of effort is put into trying to ensure that a black player reaches a reachable goal. In the case of receiver, they're forcefed the ball. But it was the opposite with Adam, he was studiously ignored. Given the racial dynamics of the Caste System it must have been felt by the Vikings organization that just Thielen reaching 1,000 yards would have angered Diggs and many other Vikings players. Blacks are hyper-aware racially, and are also often egocentric and very insecure.
Then again, maybe it was just Thielen having a bad day, all of a sudden unable to get open the Sunday following his 202 yard, 2 TD performance the week before. Both Thielen and Diggs reaching a thousand yards would have made for an "acceptable" event to celebrate. But not Thielen alone. My bet is that the black supremacist milieu of the NFL was the main factor in what took place.
