When the sales pitch for a guy that people want to trade is that he is young, full of potential, on a good contract, etc, it sounds to me like someone we would want to trade FOR. It's not like they are blocking important playing time (like Ant is), being way overpaid for their production (like Ayton), stopped giving max effort (Grant), unavailable because of injury (Williams) or just not going anywhere (Jabari, Murray, BANTON, Minaya, Reath). The focus of the front office should be solely on moving those vets for as much as possible while hanging onto the young core. If any of Deni, Tou, Sharpe, Scoot or DC get moved it just creates another hole to fill.
I don't know if it's boredom or some personal bias that makes it so easy to just throw out any of those names as a trade option. I'd rather dump the vets for pennies on the dollar, acquire some young pieces for the bench and start building continuity for the future.
