LBs lining up as CBs

So this just happened to me in CPU vs CPU, I got an easy touchdown and it looked extremelly easy so I went back to watch the replay and saw this..

No idea what formation the Broncos are in, but it looks like some sort of zero blitz type thing. No second or third level. This is not the issue though since I guess this could just be play design.

When this happened though, noticed something strange.

The MIKE (Greenlaw) was lined up on the outside across my WR2 and the WILL (Hall) was lined up across from one of my slot recievers. The WILL over the slot seems weird enough, but the MIKE lining up across the WR2 on the outside takes the cake.
