Good stuff, but there's not enough defense of Vince's speed and explosiveness. It's like they're talking about Ted Washington or William Perry. Vince? With 3 Vinces rushing and 2 Vinces jamming at the line, you're left with 3 DS in patterns with 6 VWs in zone. You can basically eliminate the short middle of the field because of passing lanes/height. You're left with QB DS having about 1 second to make a read and get a pass off, with no margin of error because of the height difference in any contested catch situation.
Plus, a wildly underrated factor is that the DS C is getting hit by VW on every snap, immediately. If he doesn't muff snaps from nerves early, he's muffing them from damage and exhaustion very quickly.
