Interesting. That's different from the Football Reference numbers, even when I click on All Competitions:Per MLS's website, which holds the official stats, Villa had 77 goals and 26 assists in the regular season (103 contributions), plus 3 goals in playoffs.
Maxi, per MLS, has 27 goals and 74 assists (101 contributions), plus 5 goals/6 assists in playoffs.
I'll have to double-check from now on. I use the Sports Reference numbers across all sports, and I know they're super accurate with my other sport, baseball. Maybe it's a little hazier for soccer.
