Collin Sexton is quickly making an impression on Los Angeles Lakers head coach JJ Redick, who has praised the guards relentless energy and competitive mindset.Sexton delivered his best performance of the young season in the Lakers 103-87 victory over the Los Angeles Clippers, finishing with 21 points and providing a much-needed spark on both ends of the floor.The guard has become known for his aggressive defensive approach and willingness to pressure opponents across the entire court, something Redick believes can help establish the Lakers defensive identity.Sometimes its hard to get his attention because he gets locked in, Redick said. Hes in the zone. I love it. I love the competitive fire. Weve seen some of the stuff defensively for our group where were like alright we can be good. We have a lot of things we gotta get better at, but we have the makeup to be a decent defensive team, if not a really good defensive team.Tonight was a great example of, we got a lot of work. You know were best offense in the league or whatever we were in the first four games. Its like the spacing stuff, timing, all that stuff, all these guys got a lot of stuff to do. But Collin, theres some stuff for spacing that he needs to work on, but I also like when hes just in go mode. It puts pressure on the defense, hes touching the paint. Those two threes that he had in the third were huge for us.While Sextons offensive game still has areas that need improvement, Redick clearly values the pressure he puts on opposing defenses, particularly when attacking the basket.His intensity was also on display during a defensive possession against Clippers guard Cam Christie, with footage of Sextons unusually focused expression gaining attention online.Redick has previously described Sextons approach as a certain level of insanity, highlighting the competitive edge he brings whenever he steps onto the court, according to Lakers Nation.Sexton has also spoken about the difference between his personality away from basketball and the mentality he adopts during games, describing his on-court approach as being ready to go to war.READ MORE: Nikola Jokic Coming For Russell Westbrook Triple-Doubles Record
