The story of Dave Nilsson cannot be told without specifying that he left MLB to represent Australia in the 2000 Olympics.  This was right after Nilsson was named to his first (and only) All-Star Game. 

Arguably, Darryl Hamilton would have better seasons outside of Milwaukee, but the first half of his career was with the Brewers where he did offer some valuable contributions.  Hamilton would bat over .310 in two of Brewers campaigns and would also have a 41 Stolen Base season.  Overall, Hamilton 637 Hits with a .290 Batting Average as a Milwaukee Brewer.

Although Jose Valentin showed better seasons with the Chicago White Sox later in his career, he did produce good power numbers for the Brewers.  He would exceed 15 Home Runs three times as a Brewer and collected 577 Hits for the team.

Charlie Moore was with the Brewers for all but his final season in the Majors.  Moore was not a superstar, but was a useful role player who played both at Catcher and in Rightfield, providing depth and leadership.  Moore would slowly accumulate over 1,000 Hits as a Milwaukee Brewer and notably performed well in the 1982 Playoffs with a .462 ALCS and .346 World Series.
