Maybe seeing Montgomery takes some time, which, nearly half the time, Fields doesn't have, don't how you can properly evaluate a QB under those conditions. Pressure is a QB's kryptonite no matter who that happens to be, Rodgers, Mahomes et. al. are terrible, fail to see open receivers with lineman constantly in their faces. Occasionally, he has plays without pressure. Not as often as he should, but sometimes. And on those plays, he frequently looks bad.
