Bagent is a rawer than most rookie from D2, never played a down in the NFL, got strip sacked for a TD his very first set of downs.
OL was the problem all game with in game injured starters and then OL players shifting all over.
Fields had not done well but knowledgeable, reasonable cappers know he had a much, much better chance of covering than Bagent.
Bears D had gotten healthy and was jelling with all the new starters brought in, and did a good job as I had hoped.
I know you like your systems but this one is a bit of a reach and you were very very fortunate with the OL and Fields injuries, surprised you do not admit it you are usually reasonable.
