Not trying to be negative here ....
JV and Ibaka have been trying to meld into our new offense quite well, even if they don't have the handles and floor awareness that our second unit has ... but hats off to them for the progress they are making in our new offense. JV is doing a significantly better job on the defensive end as well ... nice to see.
Now DD and Lowry have demonstrated some concerning signs ... while again, there has been progress, it's becomes glaring that the second unit is far superior to the ball movement and capable to play with our new offensive approach. Need Lowry and DD to get the starting unit to continue and progress with respect to ball movement. Need to see some significant progress or the playoffs may be another rude awakening. Moving a play maker to the starting unit (I like OG but the kid doesn't have handles yet) may force their hand ... fingers crossed that DD and Lowry are taking the time while they sit in 4th quarters 😉 to learn something from the kids.
Lowry and DDR were sleep walking last night. The veterans will never click as the kids in terms of new style because they are different people who need far less done for high percentage shot, but as you noted already, they've made a ton of progress and if they can keep doing that, level of pristine play will come naturally.
