The Rockies’ signing of Greg Holland — who has a 1.14 ERA, 12.2 K/9, 4.2 BB/9 and 23 saves in 23 2/3 innings thus far after missing the entire 2016 season to injury — was the best free agent move of the offseason, ESPN’s Buster Olney writes. With all the uncertainty surrounding Holland’s return to the mound, Olney writes, the Rockies focused on learning about Holland’s character. Rockies bullpen coach Darren Holmes, who, like Holland, has an offseason home in Asheville, North Carolina, was a key to the team’s attempt to find out about Holland.
