It looks like he threw at Roddy in hopes of getting attention for the contact that was going on and getting a call, which was a miscalculation because they were within 5 yards of the line, the refs were allowing a far more physical game in the 2nd half and, really, you can't put your season in the hands of an officials judgement. Roddy admitted to basically all this post game. Growing moment.
And the fumble still was a not-great snap that he took his eye off of.
