No idea how Innova structures it, but in my experience, "Captain" is 50% honorary and 50% an extra conduit for the team members to communicate with the sponsor. He might be tasked with pushing team social media stuff or organizing team dinners or team rounds at a tournament, or nothing significant at all. Not really unlike a captain on a baseball or football team. Don't think it means extra pay and certainly it doesn't automatically mean the company is saying "this is our best/flagship/most important player".
Sounds like Nate would be a great fit. Probably a better one than Paul.
The main reason I wouldn't expect Paul to leave is the fact that he was so close to winning worlds this year. He accomplished everything else. I expect he will be working overtime next season. EO, Worlds. These are definitely on the top of his mind.
