I think next season the question of Castle's contract extension is going to get very very interesting. He's arguably the second most important player on the team and a very interesting player in the sense that he generates high levels of points/rebounds/assists and his impact with Wemby is elite but his percentages and impact metrics actually crater without Wemby, even more so than other players on the team. He also has trouble scaling up his usage (turnovers/75 increase from 3 to 5.1 and AST:TO goes from 2.2 to 1.6 without Wemby this season) suggesting that his best role at this point is still as a slashing wing that functions as a secondary playmaker.
Until he's able to demonstrate otherwise, his skillset of elite perimeter defense, high level playmaking, high level athleticism, and mediocre outside shot give him an obvious future comp: Andre Iguodala. I'm not talking about Warriors Iguodala who was a little past his prime, but more Sixers Iguodala who was one of the top 5 perimeter defenders in the league and could get you 20/5/5 and offered high level playmaking out of the wing. Iguodala was slightly bigger, somehow even more athletic, but Castle's vision and playmaking as well as his rim pressure are better. Iggy also carried approximately 2.3:1 AST:TO throughout his career and shot a respectable 33% from 3. Either way, this is probably the closest comp I can think of right now. The question then becomes if you would be happy paying an Iguodala-type player a 5 year/270-280 million extension. Obviously, this is dictated by the Spurs success over the next 2 seasons and how much further development that we see, but to me at least a Sengun-like contract where he gets maybe 20-22% rather than the full 25% max probably makes more sense. This would likely put him at something like 5/210-220, which would give the Spurs additional cap flexibility.
Again, I'd be very interested to see the Thompson twins' extension this summer - Castle is a much more portable player than either the twins as his shooting has progressed further, but it should at least offer a ballpark as to where his extension next year would lean
