12, 18 and 19 got decimated by injuries.
Refs turned a 6-2 start to 3-4-1 in 2019 (Chiefs game, at Packers game, at Arizona game). 2013 was injury riddled as well. 2018 Lions beat 49ers, Cowboys, Bills and Bears if not for injuries/refs for 10-6 not 6-10
2016 was a good playoff team. 2017 was a good team as well as they got screwed over against Atlanta (runoff) and Carolina, Pittsburgh games. They were 12-4. At New Orleans was a crazy game too with Stafford hurt and all those batted ball picks.
2011 and 2014 were great teams. 2011 injuries real late in the season and refs in Falcions/49ers/Packers game turned them from division winner to wild card. Too many secondary injuries to outshoot the Saints but Stafford/Calvin played amazingly even without a RB. 2014 amazing team that the refs screwed against Dallas. L
