I'm not anti-data, but advanced stats still seem to obscure the issue rather than illuminate it.

It's like learning a new language, for sure. I find
this link helpful. Long-winded explanations are behind the spoiler tag.
Spoiler!
A CF% measures a players Corsi For (Shots For + Shot Attempts For + Defending Team Blocks) vs. Corsi Against (Shots Against + Shots Against + Blocks). A percentage over 50% for CF% suggests that the team or player has possesion of the puck more than not.
To get that CF% number compared to the team (RelTM), you calculate the team's CF% (weight the individuals CF% by Time on Ice together then average it), and you subtract it from the player's CF%. A positive CF%RelTm suggests an individual player contributes positively to his team's puck possesion.
The stats above, and most other analytic stats, are compiled based on situations. Most views focus on straight 5 on 5 play, but you can break that down for differences in road vs home games, leading and trailing, or "close" situations. My understanding of close is that it is a situation where the score is tied or within 1 goal in the first or second periods, and tied in the third period. The idea of analyzing these stats based on situation is that the style of play for a team varies based on the score. Teams with a lead tend to focus on shutting things down and end up shooting less, or teams trailing tend to take more chances and take more shots, for example.
Lastly, with regards to Zone Starts, the blurb in the glossary I linked to suggests that "Zone Start Adjusted statistics remove the 10 seconds immediately after a zone face off. It has been shown that the majority of the benefit or penalty of a zone start occurs during the first 10 seconds." So the adjusted stats remove events from the 10 seconds after a faceoff.
So the numbers I referenced suggest that, despite blocking so many shots, Russell contributes positively to the Flames puck possession in 5 on 5 situations, and especially does so when the score is close.
