Pops has been known to rest starters, so it is very very possible.
35-24 right now, roster plagued with endless injuries, and 23 games left, and they need to win 15 of those to reach 50 wins. They need to win 65% of remaining games, and their current win percentage is 59%.
You have to account for the fact that with the recent injury to Kawhi in the early beginning of the season may have cratered their W/L loss originally.
