I've often thought with all the stat processing outlets, next gen stats etc it should be easy enough to create a metric 'Interceptions QB at Fault' - take out the ones that bounce off receivers hands and maybe even hail mary's at the end of half/game that are just thrown up as prayers (advanced stat could even try to determine if receiver at fault by not running route, stopping route etc) - willing to bet Josh's IQAF would be lower than a lot of QBs he has more ints than now
