It’s not even double-teaming the check down itself that was awesome. They were also trying to goad Carr to go there. 7 DBs, fake blitz from J-Mac which was trying to lure Carr to throwing to the check down. But then he pulled back to join the coverage on the RB, and Carr was damn lucky he recognized it last minute and didn’t throw there, or that’s getting taken back to the house. But it clearly flummoxed him (and the actual 4 man rush was successful in moving him off the spot before Phillips peeled off and joined in) and he wasn’t able to recover. What a great design!
