Mark Giordano since 2013-2014 has been an elite defensive player. His suppression and goal prevention relative stats are off the roof amazing. This is while he takes some of the most difficult competition along with more relative Dzone starts in the league (On a team that has been hindered more times in the Dzone than in the Ozone for most of those seasons to present). Pretty much everyone that plays with Giordano looks far better than without Giordano (Exception being small sample size Brodie with Kris Russell during the Hartley era). Offensively even though 50+ points is a big jump from the high 30s he's produced in the Gulutzan era, Giordano produced at a 60 point pace from 2013-2014 to 2015-2016, all while having elite defensive metrics. Giordano was better than Karlsson for a portion of the 2014-2015 season. He produced at an 18 goal pace as well. I for one don't think it's a stretch to consider Giordano a top 10 Dman if he manages to score at least 15 goals and 50 points in the 2018-2019 season.
