That's the last time the Cubs lost 100 games. The current team is trying to do whatever it can to avoid being the first since '66 to reach the century mark in losses.
Ron Santo hit 30 home runs and batted .312 in '66, Ernie Banks batted .272, but Williams admits it was a tough season.
"When you lose 100 games, not too many guys have a good year that year," Williams said Wednesday.
The '66 team was Leo Durocher's first year as Cubs manager.
"It was a rebuilding process, like this," Williams said, comparing his team to the current club. "At that time, you look at it as a rebuilding baseball team."
