Taco is Love, Taco is Life
Realized we didn't have a thread, and considering I'm trying to go into hockey analytics/data analytics for a career change, I thought it'd be good to have this thread, just for any hodgepodge of analytics talk anyone wants to have.
----------
My first bit of work from the past 4 hours - Analyzing Zacha during the '19-'20 season, using With or Without You (WOWY) metrics (all situations). Idea was taken after seeing HockeyViz had data available, but I didn't want to pay for the Patreon lolol. Also used Natural Stat Trick as a reference for raw data.
Keep in mind, that the data is very limited, as it's only from this season (w Hynes is ~22 games, w Nas is ~40 games).
In summary, WOWY is an attempt to measure impact of a given player, relative to another player. What you see graphed is the CF/60 against the CA/60 in the games sampled.

Under Hynes
From the graphs, we can see that Bratt was actually better with Zacha during this ~22 game stretch, generating ~12 more CF with him. Obviously, Zacha benefitted the most from playing with Bratt, as his CA/CF #s were horrendous, but keep in mind he was also playing a good chunk of minutes with Simmonds and Wood, though he found himself with Bratt the most.
The spread with Gusev isn't as extreme, which makes sense considering Gusev struggled earlier on in the season (12 pts under Hynes, 32 under Nasreddine). That being said, Gusev is still clearly the better player, and them playing together averages out their performance.
Under Nasreddine
As you can see from the chart, Zacha is just an abysmal player without either Bratt or Gusev. The CA/CF ratio is really bad when he's without either of them. But a large amount of his time under Nas was spent with Hughes and Wood. Zacha/Bratt/Gusev didn't become a line until 2/20, which only left them 7 full games together. We can see, overall, that Zacha was a positive-impact player on Gusev under Nas. The impact on Bratt looks negative, but I believe it's because Bratt played a lot of positive Corsi time on the top line (without Zacha). Overall, Zacha does help on the defensive end, but maybe not as much offensively.
Where I think the magic is is in the ~10-game stretch these 3 had together. In summary, they as a unit were more than the sum of their parts. Their CF% (all situations) was a 56.17%, which may not seem like a lot, but considering the team CF% WITHOUT these 3 in that span of games was a 42.94%, they did pretty well. Gusev, while amazing in his own right, is just not as good without Zacha to help him out defensively.
----------
In summary, I think I'm willing to give Zacha the benefit of the doubt based on these #s, and my two take aways are:
1. These three should continue to build off the chemistry they have. One common trend in these two charts are that Zacha does add the defense, and in some cases can help offense, and I don't know if I want to mess with that.
2. Keep Zacha and Wood away from each other. It doesn't work.
