One of the most underrated players was Brian Giles, who played for three mediocre teams (Cleveland, Pittsburgh, and San Diego) and did not see as much love as he should have.

The Outfielder played his first four seasons (1995-98) as an Indian before he moved to the National League with Pittsburgh, and in his four full seasons as a Pirate, he never had less than 35 Home Runs, 95 RBIs, or a .298 Batting Average.  His On Base Percentage was over .400 in all of those seasons and received at least one MVP vote.  

The Pirates traded him to San Diego during the 2003 season, and while his power declined, his plate discipline remained strong, as he led the NL in Walks in 2005.  Giles played until 2009, and he retired with 1,897 Hits, 287 Home Runs, and a career Slash Line of .291/.400/.501.

The younger brother of Baseball Hall of Famer and New York Yankees legend Joe DiMaggio, Dom DiMaggio, was quite the player in his own right.

Cecil Cooper is mostly known for his work with the Milwaukee Brewers, but the First Baseman had a very healthy career in the Majors beyond what he accomplished in the state of Wisconsin.

Cooper began his Major League run with the Boston Red Sox, where the First Baseman was a star on the rise who helped the Red Sox win the American League Pennant in 1976.  The Red Sox traded him for George Scott, and with all due respect to Scott, it was Milwaukee who won the trade.

With the Brewers, Cooper played 11 seasons and was an All-Star in five of them.  Cooper batted over .300 in his first seven years in Milwaukee, and he would also lead the American League in Doubles twice, RBIs twice, and he had five 20 Home Run campaigns.  From 1980 to 1983, Cooper finished in the top eight in MVP voting and was one of the leaders of a Brewers team that reached the 1982 World Series.

Cooper retired with a .298 Batting Average, 2,192 Hits, 241 Home Runs, and 1,125 Runs Batted In.

One of the better players of the 1970s who seemed to fly perpetually under the radar was Andy Messersmith, who finished in the top five in Cy Young votes three times.
