The spurs lack a floor general. Last year the spurs played much better with tre jones than without because Tre can set up simple plays and direct traffic. It’s not a surprise they are that much better with CP3 in place this year.
For all the issues people have with the roster, what the spurs need to figure out is who will be the future point guard and who will be the backup. Lots of talk about dumping tre jones but he is an excellent backup point who was shoved into the role of a starter last season. With CP3 in place tre has done reasonably well (outside of scoring) in very limited minutes this season. While most think castle will be the long term starter I still think he’d absolutely shine in the point forward role. He’s strong enough to handle most SF, he’s relatively athletic, he can guard PGs so we can afford to have a PG who isn’t the strongest defender and hide him somewhere else (ahem Fox).
CP3 won’t be effective for long, even if he decides to stay one more season the starting PG role is a glaring hole to me.
