4. Dexter Fowler
This is a double entry, as the Cubs signed Fowler to two one-year deals in 2015 and 2016 respectively. Those wound up being two of the best seasons of Fowler's career, not only from a personal standpoint but for his contributions to the success of the team. The endearing moniker from manager Joe Maddon "You go we go" perfectly summed up the ability for Fowler to set the table while hitting in the 1 spot in the Cubs lineup.
He was instrumental in getting the Cubs on the board early, and this skill showed itself in Game 7 of the World Series with a solo homer off of Cleveland ace Corey Kluber.
