What I know: Mark Pope stinks at WR. Unplayable most of the time.
What I don't know: How Mark Pope would look playing corner.
I'll take the unknown quantity here on what is otherwise a wasted roster spot.
The more successful WR to CB position switches that will most often be mentioned got more physical as corner than they were as wide receivers. So much so, most of them are known as pretty physical corners in the NFL. Pope will never be a bump n run corner or ever be described as physical, but maybe he can be a decent 4th corner on a team that lacks depth on the position. He stinks at WR and anyone can contribute what he's given us (even the rare good play could be replaced with anyone). He's replacement level. But we could use depth at cornerback. You never know. I'll take the dice roll and if he sucks there, he sucks there.
