Editor’s note: The Chronicle is reviewing the 2018-19 season of each Warriors player.

Warriors point guard Shaun Livingston often calls this stage of his career “house money.”

Twelve years removed from a knee injury so gruesome that doctors briefly considered amputating his leg, Livingston, 33, is just thankful to still be walking — much less, to have won three NBA titles.

His achy left knee serves as a near-constant reminder of all he had to overcome to reach this point. As he weighs retirement this summer, Livingston feels at peace knowing his story provides an example of perseverance for any player who faces a career-threatening injury.

What many NBA fans might not know is that, just to suit up for Warriors games last season, Livingston had to spend hours each day with the training staff. His pregame routine included a rotation of ice and a heat pad on his left knee, leg stretches and muscle-building exercises.

Even then, Livingston often returned to the locker at halftime to find his left knee swelling. Periodic rest days weren’t enough to keep the pain from worsening significantly as the season progressed.

Livingston played 64 regular-season games, his fewest in six years. Although he shot 51.9% from the field, Livingston’s scoring average (4 points per game) was a career low and his assists aveage (1.8 per game) was a tenth of a point off a career low.

In the past, Livingston had purposely eased into the regular season, ensuring that he was at his best for the playoffs. But when the postseason arrived this time, he had little left to offer. His 4 points, 1.4 assists, 1.4 rebounds and 45.3% shooting were career playoff lows.

Offseason outlook: Only $2 million of the $7.7 million in Livingston’s contract for next season is guaranteed. The Warriors, who could be staring down a $375 million payroll, might not want to endure that $5.7 million hit for a past-his-prime point guard with chronic knee pain.

If Golden State waives him before all $7.7 million of next season’s contract becomes guaranteed Sunday, Livingston will almost certainly retire. As he told The Chronicle in April, “I’ve been able to accomplish some pretty cool things. I reached my goal, as far as making it back into the league (from a severe knee injury) and obviously being a part of a championship team.”

Livingston would rather start a career in an NBA front office, perhaps with Golden State, than sign a veteran-minimum contract elsewhere. Livingston has already talked to Warriors general manager Bob Myers about potential opportunities.
