Let's be honest. Zimmer loves him some defense. That's where he wants to keep his focus. That's where he wants to put the emphasis on winning games. The offense to Zim is like a hobby you do once a month, for fun, with your drinking buddies. The defense is why he gets up every morning. Zim would sacrifice the offense to make his D legendary. I think it's Rick that pushes the emphasis of Offense to Zimmer. I'd love to be a fly on the wall of Rick's office, if he told him "We are going to get Cousins, but we'll lose the ability to pay Barr/Waynes at the end of their 5th year. Start looking for their replacements". (The veins in Zim's temples would be the size of wallnuts) lol
