Jeff Cirillo was only a member of the Colorado Rockies for two seasons, but it was an impactful one.  Cirillo was an All-Star in 2000, a year he accumulated 195 Hits with a Slash Line of .326/.392/.477.  His second and final year in Colorado was almost as good with 165 Hits and a .313/.364/.477 Slash Line.  That year, he had 17 Home Runs, the best of his career.

A decent Shortstop, Clint Barmes is more of a trivia question in Rockies lore as he was the starter in that position prior to Troy Tulowitzki.  Barmes still had four seasons where he had more than 100 Hits, one of which saw him smack 23 Home Runs, the most of his career.  Defensively, he would have a 3.2 bWAR in 2006, which was good enough for second in the National League that year.  Barmes played for Colorado in 665 Games over eight years.

The career of Jason Jennings was not a long one, but it start off spectacularly with a Rookie of the Year in 2002 with a 16 and 8 record.  Jennings never had another winning record after that, though in 2006 he did finish 8th in 2006 for bWAR for Pitchers.  Jennings still finished his Rockies career with a winning record (58-56) and had 622 Strikeouts.

Dexter Fowler would win the World Series in 2016 with the Chicago Cubs and did so in a starring role.  That star first began to shine in Colorado.
