Here's the thing..... Sochan will never be anywhere as good as KD, even a 37 year old KD. His upside is really good glue and energy guy with some defensive stopper side to him. Like a bankrupt Draymond Green. The advantage to keeping him is if his mindset is right (and thus far it hasn't been) is he won't need many shots or USG and his price. But right now, Jeremy Sochan isn't a very good player. He's a good talent and we all hope he takes the next step forward but he doesn't do anything well. He doesn't rebound enough or play on the ball defense enough to reach to good levels. He shot better this year but he's still a dismal 3 point shooter. Doesn't block shots or control the paint. Doesn't create extra possessions by causing turnovers or stealing the ball. Basically, he's just potential and it feels like the Spurs haven't really known what to do with him. I think it's easy..... Rodman with a 3 point shot should be the goal. He'll never be that good on the defensive end or on the boards, but that should be the goal and he's not really in the same state yet, so let's not mention neighborhood.
So, while I get it, let's try not to suffer too much from foundation bias. It happens to me too, so again, I totally understand but there is a real possibility that 6 or 7 years of Sochan never delivers as much VORP or WS as 3 years of KD at this age. But it's the money, man..... it's the money. KD takes up so much room that your either can't give up as much as Phoenix apparently wants or his extension would have to be a self-aware hometown discount. Something around 2 for 70m or something. You basically give KD 65 games during the reg season and pray he's healthy and has his legs for a deep playoff run.
Again, all of that said, I think we get outbid by quite a bit.
