I'd never thought I'd be saying this but yeah, there's really no place for him to run to. He'd probably only take a factory seat, and of those you've got KTM bringing growing their own alien in Acosta and good factory riders getting results. Yamaha is definitely not in a good spot either. Ducati has talent oozing from every bike. Suzuki doesn't exist anymore. The only seemingly half viable option is he takes Aleix or Mav's seat at Aprilia. But they ain't gonna pay a $10+ mil salary and crew. He's gonna ride that Honda past it's limits until it retires him in a hospital.
