I don't think any of them have reached franchise sentimental leader and identity of the team level lol.
I did an example with Middleton here

In trade, yeah it's not going to be cheap, but worth it IMO. You can't bet on Manson being this good, and healthy next year, but if he continues, and has a good playoff run he may actually have value to a bunch of stupid GMs.
I bet the right shot Manson replacement is even harder to get, and you HAVE to replace him IMO.
