It's not working anymore, we've seen what this is gonna get you, you have to try something else. I don't think it's as simple as pointing to Rudy and going "He's the whole problem", blame can be shared and we gotta share some with the coach putting him in that position.
If your defensive gameplan is falling apart because your best defender is being hunted and fried alive, you either need a new best defender or a new gameplan. Maybe both.
