So much of this rides in how MATFO feels about the shooting upside of castle and Harper. If they felt both of them can work up to average shooters or better, then I’d say them and wemby will be clear foundational pieces for the next decade, so all trades should keep this in mind and keep assets that would allow them to have cheap high end role players (read Hugh floor rookies) to cycle through.
However, if the view is that they are who they are and they are not long term foundational pieces then the focus would be to trade one of the two and get a big piece in return that would’ve foundational, and forgoing future flexibility if need be.
I’m in the former camp and think we should be looking at the Hausers and the ellises instead of the Giannis or even the Trey Murphys.
