Every QB, except Watson, under Stefanski has proven to be above average. Browns are designed to win with above-average quarterback play.
I'm confused by what you mean by this. Are you saying they played above-average with KS, or that they were all above average QBs? I believe Brissett has been benched for a rookie (albeit, a highly-drafted one), and Flacco has also already been benched after coming in mid-season.
I understand that people see potential in DTR, but so far results have been below average.
