Number 27- Story
Garrett Atkins also wore #27 for parts of six seasons but in just four seasons, Trevor Story is the winner. Just by bWAR, Story was better in 2019 than Atkins was in all six of those seasons combined so it wasn’t particularly close.
In four seasons, he has hit .276/.341/.537 with an OPS+ of 113. He has also accumulated 40 DRS and a WAR of 18.6. In the last two seasons, he has been an All-Star and won a Silver Slugger Award in both seasons and he came in 8th and 12th in NL MVP voting.
Number 28- Arenado
By total WAR, Aaron Cook is the second-best pitcher in Rockies history but he is no match for the player that, if he plays out his entire contract in a Rockies uniform and stays as healthy as he has been before, will be the best player to ever wear a Rockies uniform.
If you’re reading this, you likely know how good Nolan Arenado is but in case you don’t know, in seven seasons, he was won seven Gold Glove Awards, five All-Star appearances, four Silver Slugger Awards, led the NL in homers three times, RBI twice, and come in 8th place or higher in NL MVP voting in each of the last five seasons.
