Saints could get to $14.61 million under the cap without restructuring Derek Carr, after Saints salary cap potentially increases by $5M

This bribing solution has been my favorite solution so far. It's actually brilliant.

Give him $5-10m guaranteed right now to lower his base to vet minimum. Then cut him with a June 1st designation. He gets the cash and the ability to go get a new contract. We only have to carry $27-32m until June instead of the full $51m. Split his dead money over two years.
I keep seeing this over and over by many posters and I'm confused.

We cut Carr and still have to pay dead money after he's gone.
Meanwhile, Carr is the best QB on the roster. Pay money to the best QB you have on the roster not to be here.
Unless they plan on signing another veteran for yet even more money.
I don't see a veteran out there who's going to come cheap. More money problems ensue.

And I'm not even close to being a Carr fan.

Help me out here.
