Did you not actually read my post? Limiting Philly's possessions doesn't matter if they keep matching your scoring. NE got the ball to start the half and scored a TD, making it 22-19. Then what did the defense do? 85 yards, TD to go ahead 29-19. NE cuts the lead again to 29-26. So this defense made a stop here, right? Nope, 51 yards, FG to push the lead to 32-26. NE TD and they finally have a 33-32 lead. So NOW the defense finally makes the adjustment and play, right? No. 75 yards and TD to pull back up 38-33.
So... how is that better than the 1st half?
What you are failing grasp is that limiting Philly's possessions also means limiting the Patriots possessions. That is the OPPOSITE of what is needed when trailing by multiple scores. You want to maximize possessions, which also means increasing Philly's possessions. The fact that Philly had essential 3 possessions the entire 2nd half doesn't bode well for the defense, because it means Philly went on long, clock killing drives. It's literally opposite of how your thinking. More possessions by virtue means you are making spots. Fewer possessions mean you aren't...
Those 3 drives took a combined 16 minutes. That's out of 28 minutes (before Pats possession that ended in the fumble). Philly not only basically matched the Pats scoring, but also possessed the ball 16 minutes to 12 minutes for the Pats... Again, how is anything other than the worst possible outcome defensively?
You simply can't make a comeback without making stops. Limiting possessions just doesn't work if they match your scoring... This isn't that difficult of a concept...
