I should clarify, when I'm talking about mid-level, I am talking about mid-level contracts, rather than player skill or 'value'.
Edit: Wiggins is an interesting example, because compared to his current contract he's already taken a pay cut to sign a longer deal with Golden State (after making 33 million this last season, he'll go down to $24m. in the upcoming 23-24 season, roughly 18% of the cap) - although his agent did get him a player option in the final year.
