This feels like a really weird thing to argue. If the man can manage 60 points on the worse team in the league, he can manage that with any team. 66 last season. 60 in 2023-24. 64 in 2021-22 with Nashville. If he signs with a stacked team and isn't getting top minutes, sure his production might fall. So he'd be wise to sign with a team that has an opening in the top 6.
If those are teams you are talking about, if those are the teams that are low-balling him, I see no reason why he'd want to entertain those offers just to place reduced minutes. He'll get a decent offer. The other things you are leaving out is your expected term. At 33, he's not getting a 7 year contract unless it is to defer cap. Which then sure, I can see him get a 7x 5 contract. But that's effectively like $10M for the next 3 years. Unless he can harness the powers of Jagr and be effective till he's 40. But then, why would you want him on the books for that long just to get a smallish discount?
