This will be unpopular, but I believe there is some merit to the following IF/THEN logic.
IF the injured and inept OL is the cause of Mac's issues,
THEN Matt Patricia's effectiveness as an OC is also being compromised by that same OL.
It is being argued that we cannot judge Mac because the OL uselessness. There is some validity to this. Some will say Mac is trash anyway. Others will say very few QB's could do anything with this line. Bottom line, how many plays have we witnessed this year that were blown up by garbage OL play? Well, that affects Patricia as a perceived play caller just as it affects Mac as a QB. As someone already mentioned, if Sean Payton was the play caller this year, it wouldn't matter. If true, we can't really judge Patricia then.
