Yes we can blame Mac. It's always an excuse, this guy is injured, this guy is missing, if we only had this guy, the line us awful.
I think Mac has proven he makes bad choices, heck they barely let him throw after opening it up the beginning of last season and him being a turnover machine. Who remembers the buffalo 2 pass game?
We changed the coordinator, same result. Not just a slow offense, it's outright probably one of the worst. Look at first half scoring. Mac is bad. Unfortunately bb put himself in a position with no likable backup. He was willing to let zappe go, he raided practice squad players. This season is a wash. He's gonna need to either pay for a QB or draft 2 and sign a mid level vet.
I don't see how you can blame O'Brien. Mac is the common denominator.
Blame Mac
Blame personnel (line). Was the outright biggest need outside of the QB and totally neglected.
