They have already screwed it up. They likely could have gotten him signed for 250 - 300M 2-3 years ago. Now it’s going to cost them 400-500M. Or they lose him for nothing.
They have already cost the team hundreds of millions.

They needed to lock him up before going big game hunting. Especially considering that they missed.
