Elgin Baylor played only 48 games of the 1961-62 season, out of 80 team games. This wasn't a result of any injury, he was an army reservist and called up to active duty midway through the season. He played the first 42 games, then just a handful of the others when he could get a weekend pass.
With Elgin in the lineup, the Lakers were 37-11, scoring 120.6 and allowing 116. Without him they were 17-15, and were outscored 115.4 to 116. In both cases they won more games than expected, as they won 54 games despite points/points allowed numbers that would normally add up to 45.
Per 48 minutes, Elgin's estimated impact was 6.7 points.
