I don't agree with 3 out of 4 of those. Against the Titans he slipped after getting us in position for the win. One could argue he actually got the first down the play before which was originally called a first down and the changed on the field.
Vs Patriots the first time, was more so about bad playcalling from Daboll. Allen made some excellent throws into the wind and if Diggs doesn't drop the deep TD that was right in his hands, we probably would have won the game
Vs the Patriots, neither him nor the offense or team for that matter played well at all. Allen played his heart out in the second half and willed the team to be able to tie it up. The defense gave up the big TD in OT.
The only game I will agree with you on was the Jaguars game which he played bad. But I think putting this on him for all of these games is harsh. You have to take into account every factor
