He is trash , older and coming off of an Achilles injury. Send pressure up the middle and he will fall like a baby. Saints do better against traditional QBs than a running one.
Maybe not the full extent, but my thinking is definitely along these lines.
Cousins is/was an above average QB. No doubt. But he's not getting any younger, AND he's coming off of a season-ending injury. Our defense is much worse against mobile running quarterbacks, and Cousins has never been that, and certainly isn't going to start now.
Yeah, it's decent competition, but nothing I'm really scared of.
