When Marrone was hired, he said the coordinators he brings in will be experts in their field. While we can say that about Pettine and Schwartz, and maybe Crossman this year, there's no way anyone can confidently say Hackett is an expert at being an OC. With that being said, how much credit should Marrone get with this year's 9-7 record? Should he get credit for hiring Pettine, Schwartz, and getting players to help out Crossman on Special Teams? One thing is for sure, he is a former offensive linemen and former OC and the offense, especially the O-line has regressed significantly.
