I think once the playoffs start, we'll get the answers to some of these questions.
In theory, Mitch can be doing with Castle exactly what Pop was doing with Sochan - force feed him touches to try and develop him in the regular season to try and unlock something for long term benefit. Spurs may still be treating this year as a "development year" with the goal of making the playoffs. They've blasted past that goal so far, so they feel like they have a cushion to experiment, and force feeding Castle and trying to unlock his on-ball creation is one part of the development process. No idea wtf they're doing with Harper's minutes, but if they feel like Harper had a ton of on-ball reps in college, they might try and develop him as an off-ball weapon first, again to have him do something he's not used to to make him a more 'well rounded' player.
Pretty good theory, you could be right.
Personally, I'm not sure why they're not just giving Castle the Dejounte Murray treatment, especially with Mitch's close relationship with Murray and his successful development - have Castle lean into becoming a defensive weapon first, then gradually feed him on-ball touches over time as his jumper improves.
This is yet another reason why I think there is some sort of agreement. I would have expected them to take a part closer to what they did with Murray than the opposite way. Maybe they really do believe in Castle's potential and are trying to see if the can unlock more of his game.
Then once you hit late regular season into the playoffs and the games start mattering, shift a lot more playmaking burden to Fox and dial Castle's on ball usage back to maximize your chances of winning games. Pop teams were famous for having mediocre regular seasons where they'd underperform, then ramping up closer to the playoffs and Mitch may be doing some weird variation of that where he's keeping everyone's minutes down for most of the regular season and slowly ramping up as the season goes on. I don't know, this might be pure cope on my part, we'll see what happens later in the season.
Well, that sounds good and I hope we get answers before then. The difference is that the Spurs teams with TD were legit playoff teams and contenders and not unknowns like this Spurs team was before the the season started. It's a good strategy if that is the way they're playing it. I'm just not sure they're doing that this time around as they didn't really even know if they're a playoff team before the season started. I'm sure they expected to make the playoffs with all the talent they have, but until proving it on the court, I don't think they were certain of a playoff spot which might have left them open make a promise or two. Hopefully they're doing what you said, though, and are building towards the playoffs and start tightening it up beforehand.
