The enthusiasm in Steve Nash’s voice sounded infectious. His smile widened as he spoke. And the Lakers guard appeared relaxed after nearly completing a week of training camp in which he flourished on the court without injuring himself.

Nash has spent the past four months in this state, reporting “no hiccups” this past offseason while healing the nerve root irritation in his back and hamstrings that sidelined him last season for all but 15 games. So even if Nash described his past two injury-riddled seasons as a “nightmare,” the Lakers’ 40-year-old point guard seemed as excited as an unproven rookie eager to crack an NBA roster.

“Because it’s so tenuous, I never act like I’m ready to go and am past everything,” Nash said in an interview with this newspaper. “I’ve gone through too much to feel that way, but I feel good.”

Nash could hardly describe himself the same way a day after saying those words. He missed most of Saturday’s practice after rolling his left ankle on the foot of rookie forward Julius Randle during a conditioning drill.
