The last time the San Antonio Spurs played a playoff game without Tony Parker, they were getting swept by the Los Angeles Lakers in the 2001 Western Conference finals four championship runs ago.

Now, 16 years later, they will be without him again after he ruptured his left quadriceps tendon on Wednesday, an injury that will sideline him for the rest of the postseason.

Nearing age 35, Parker may no longer be the same driving force he once was for the Spurs, but his performance has remained a crucial indicator of the team's success.

How will San Antonio replace Parker, and how much drop-off will they see in a tight series against the Rockets tied 1-1 heading to Houston?
