To play off that post:

This is 35 seconds left in the 2nd Qtr. They give a textbook tampa 2 pre-snap look with the 2 high safeties, deep LB and press coverage on the single receiver side.
They're trying to bait a throw by CK.

generally, the QB's read on a tampa 2 will be the MLB. He's going to look to make sure the MLB is taking a deep middle drop - that changes the coverage between a "tampa" 2 created by Tony Dungy or a regulard cover 2 zone. So, at the snap the MLB takes a deep middle drop - shading towards the multiple receiver side - trying to show a "tampa" 2 look.

What I've done here is try and show how they are baiting the throws. The yellow is where they're playing. The Red is where a typical "tampa" 2 coverage will be. You can see how they are trying to show the tampa 2 and then play all the holes of the tampa 2. They're trying to bait a throw into the usual holes of the tampa 2 so they can either make a stop or an INT. That's something Greg Williams does from time to time. When he was with the Saints, he did something very similar to this against Peyton Manning in the super bowl. The problem is, CK doesn't bite it.

Because they're playing so aggressive on the underneath routes, the corner bites on Lloyd's double move.

After he bites, the corner is effed. The deepest guy to help him is a MLB..... no help.

Lloyd gets separation and the rest is history.
It's a big risk/reward defense - which they lost big time. This was the turning point in the game. But, you see how the Rams were trying to bait us.
