Not that QB rating is super accurate but I can think of multiple games off the top of my head that were worse. 2006 at home vs Vikings. I believe his qb rating was 3. Also 2006 at home vs Packers. It was 0.0 in that game. The “horsefeathers it I’m throwing it downfield game” against the Patriots was really bad too Edit: just looked up those specific games MIN - 6/19 for 34 passing yards, 0 TD, 3 INT GB - 2/12 for 33 passing yards, 0 TD, 3 INT (only played the first half) NE - 15/34 for 176 passing yards, 0 TD, 3 INT Heck the famous MNF game against Arizona he was 14/37 for 144 yards, 0 TD, 4 INT 2007 vs Dallas - 15/32 195 yards 0 TD, 3 INT What about Cutler? 2009 vs BAL: 10/27 for 94 yards, 0 TD, 3 INT 2010 vs NE: 12/26 for 154 yards, 0 TD, 2 INT 2011 vs CAR: 9/17 for 102 yards, 0 TD, 1 INT 2012 vs GB: 11/27 for 126 yards, 1 TD, 4 INT I thought the question was a joke. Grossman literally had 5 games worse than Fields' today in a 13-3, Superbowl season. Grossman also had a very good O Line, decent WR, decent TE plus a championship caliber defense, and the greatest KR/PR in history to mask his terrible play a bit. Not giving Fields a pass, before the season I thought it was 50/50 he would be a bust, now I am thinking its more like 80/20
