I feel our defense has improved A LOT over the last few games. Guarding pick n roll much better - which UCLA does a lot.
UCLA guy here. First of all, UCLA doesn't really run pick and roll much at all. They run a fluid motion offense. They like to run Alford off baseline screens where Ball can give it to Bryce or hit Welsh for the 15-17 foot pick and pop.
UCLA's defense improved rather dramatically (eyetest) since switching to 3-2 zone with Lonzo Ball at the top. We don't have the overall athleticism with Alford and Hamilton on the floor to ever be better than a decent defensive team, but the defense isn't the sieve it once was. The bigger problem in the second half of the schedule was the regression of our offense. Isaac Hamilton was in a major funk until the last two games, Aaron Holiday has become a low bball iq turnover machine, and now Bryce Alford can't seem to hit the broadside of the barn. Much of this is because teams have finally learned how to defend UCLA: face guard Bryce Alford behind the three point line with an athletic defender, run Holiday off three point line and make him a driver, and play Lonzo to pass instead of shoot. You do all of the above, and UCLA must get the ball into Leaf and Welsh's hands in the post and play inside out. However, UCLA just refuses to stick with that approach since their DNA is to gun threes and they can easily shoot themselves out of a game against a good team. This is what happened against Arizona and USC in their losses. Having said all that, we did go 10-1 over our last 11, including wins over Oregon, Arizona and USC (twice), and we can still be dangerous and give UK and UNC trouble if Coach Alford can make a few tweaks to the offense this week.
Anyhow, good luck to you fellas. I hope we both get through the first weekend, which is no given with Wichita State, Kansas State, Wake Forest and Cincinnati potentially on our teams' plates.
