Wilson and Mahomes had and have good offensive lines. I believe that is being overlooked here. I don't believe Trubisky has ever had a good OL maybe his first year but each year after that it has been bad and this year is just awful. Go back to Couch and one other that I am forgetting that set the record for being sacked or hit. QB's are only as good as their offensive lines if the OL is bad your QB is going to be bad. The same goes for the RB, WR and TE positions especially RB. I believe OL is far more important than the QB everything in football starts with the OL.
