Troll thread?
You're quite off here I'm afraid. Finishing is of course a thing, an important thing.
Both getting there and finishing are important skills for a striker. You have good finishers (Kane, Haaland, Son, Messi) who is consistantly overt time outscoring their xG and you have bad finishers (Solanke, Watkins, Jesus etc.) who consistantly underperforms their xG. Consistantly scoring 1,15 goals from 1,0 xG is better than consistatly scoring 0,85 goals from 1,00 xG.
Take for example these two strikers who has produced the same xG/90 in their careers:
Jesus:
0,66 xG/90
0,48 goals/90
Kane:
0,66 xG/90
0,76 goals/90
Kane's scored 58% more than Jesus from the identical generated xG/90.....over a career.
Please explain to me how finishing is not a thing?
And no! Not everyone will end up around their xG eventually. Good finishers will outscore their xG (Haaland, Kane, Son), bad finishers will underperform it (Solanke, Watkins, Jesus, Mbeumo, Toney etc.). Most strikers in the top 5 leagues are "average" finishers (+/- 3-4% of their xG) though, but that doesn't mean the outliers doesn't exist or is a thing.
Fun facts:
Messi was an elite finisher his whole career, but also had great shot volume (5,46 shots per 90 for Barca) and 87% of his open play goals came from inside the box.
Messi averaged 0,89 non penalty goals/90 from 0,72 npxG/90 for Barca in LaLiga between 2014 and 2021
Ronaldo underperformed his xG in 6 out of his last 8 seasons in Spain, Italy and England. He was an extreme shot volume guy. Noone's had more shots per 90 while that's been recorded (averaging 6,4 shots per 90 for Real Madrid the last 4 seasons he was there) and 93% of his open play goals came from inside the box.
Ronaldo averaged 0,88 non penalty goals/90 from 0,84 npxG/90 for Real Madrid in LaLiga between 2014 and 2018
To put that in perspective:
Haaland has averaged 4,15 shots per 90 so far for City and 89% of his open play goals came from inside the box in the PL.
Haaland has averaged 0,90 non penalty goals per 90 from 0,80 npxG in Bundesliga and the PL since he moved to Dortmund in 2020.
Kane averaged 3,93 shots per 90 for Spurs and 89% of his open play goals came from inside the box in the PL.
Kane averaged 0,60 non penalty goals per 90 from 0,52 npxG in the PL.
Messi and Ronaldo both had direct freekicks though, which inflated both shots and goals numbers a bit.
