As the LA Clippers return to the postseason hoping to erase stinging memories of last year's playoff collapse, Kawhi Leonard feels "confident in this unit" and says the Clippers' success will come down to how mentally strong they will be.

As the fourth-seeded Clippers prepare to play the Dallas Mavericks in the first round for the second straight year, Leonard stressed the importance of his team being sharp mentally and motivated to do whatever it takes to win.

"It's just about between the ears now," Leonard said when asked about the feeling with this Clippers core entering this postseason compared to last year. "How much are we willing to sacrifice to get a win? How much of our mind and body are we going to put into this playoffs? That's where I'm at. I am confident in this unit."

Last postseason, the Clippers eliminated Dallas in six games before blowing a 3-1 lead in spectacular fashion and losing in the second round to the Denver Nuggets. After that meltdown, Leonard said the team needed to improve its basketball IQ, ability to know what to do when plays are taken away from the offense and adapt.

The Clippers made changes after that, replacing coach Doc Rivers with Ty Lue and revamping the rest of the coaching staff. Montrezl Harrell and JaMychal Green left in free agency and the team added veterans like Serge Ibaka and Nic Batum before trading Lou Williams for Rajon Rondo at the trade deadline.

Lue balked at the notion that the Clippers face immense pressure to win a championship after failing to meet enormous expectations last year as favorites to win it all.

"Last year was last year," Lue said. "We have a different team, we have a different formula, we've done things differently. Our team is healthy. We have made some changes. So we are a totally different team. That doesn't necessarily mean we are going to win a championship because of that, but we are in a different place."

"Pressure to me is something totally different," Lue added. "It's growing up where we come from as kids, not knowing where your next meal is from or your lights or water is going to be cut off or if someone is going to be shot on the next block over... If we don't play hard, don't compete and don't bring it every single night, those are things you can't live with. I don't see any pressure. I think our mindset is totally different from last year and we are ready to go."

Like last year, however, the Clippers have had injuries disrupt their continuity and ability to form chemistry. They haven't had their whole unit together for an extended amount of games entering the postseason. Their two stars also have injuries that they've been managing.

Paul George had to miss time earlier this season with a toe issue that he is playing through. Leonard missed nine out of 10 games with a foot injury in mid-April, and he said that the injury was something he has had to deal with.

"I feel good," Leonard said when asked about his foot. "I am ready to go. I will be capable enough to play."

And Leonard says he likes what he sees in the Clippers entering this postseason.

"I feel good," Leonard said when asked about how he feels about the team entering his second postseason with the Clippers. "I feel confident like any other year. I feel like we got a good team. We got some depth on us."
