I thought it was Cover-2 and McD doubled the slot, but it was cover-6 and eveyone did their job, it was good route, good throw and good catch

They showed single high presnap, then during cadence they made it look like cover-2, the boxes on the 2nd shot are 5 under, 2 deep

but the #1 WR on top is m/m by corner

McD, by rule covers the #2 receiver if it is a vertical route, and it was

underneath there are 4 short zones and Mo has deep 1/2 on the near side.

So, #1 on top is M/M, the #2 receiver is doubled by the short zone and the SS, everyone else takes the man in their zone, or simply zone coverage.

Wilson read it, knew the outside receiver was m/m and threw it...it was worth a shot.
