When my opponent is playing only 1 WR I want to put only one CB on the field, but:

1. Is that matters on which side I will put him, I mean:
a)my CB will go to the side of the opponent WR
b)or he will stay on his side and the WR will be covered by... he will be uncovered...

2. When there is 3 WRs, with slot WR, who is covering the slot guy? Is two receivers on that side covered by one corner or outside linebacker/safety will take over one of WRs?

As we already menitoned, we will add the exact information about player position (left, right) into the match report after the translation system is done.

The side of the player in this case (WR vs CB) does matter. If the opponent is attacking with one WR on his left side, then the defender must place CB on his right side.

SF covers the middle no matter who runs in.
