I wouldn't be opposed to Clady making top-five money with incentives, but he'd have to play a season and show he's completely over his injury and back to form in order to receive that straight up.
Really though, his floor is probably above average. The more I think about it, the less I'd care if they paid him more than he's worth right now. The way contracts are constantly growing each season almost forces teams to estimate market value down the road when paying players now, and if they overpay him now on a six or seven-year deal it will probably end up being a fair price in two or three years.
This is all assuming he stays healthy and doesn't forget how to play the position.
