While it is not entirely impossible that Wilt could average 8 to 10 assists in today’s game, it is not very likely.
People remember the year Wilt led the league in assists, but forgot that he averaged less than 5 assists a game 10 out of his 14 years in the league, and while averaging 5+ assists in any season in the NBA for a center is phenomenal, it doesn’t go near 8 to 10 assists per game.
On top of that, it wasn’t tougher for the league to get assists back in the day. The league was seeing 9.1 to 11.5 assists a game for the league leaders back during Wilt’s days, and Chris Paul averaged 11 assists per game last year. The league was also averaging around 20.95 to 25.2 assists per team per game back in Wilt’s game, but 21 assists last year.
Also, when you look at Wilt’s assist leading year. He led the league in assists totals, not average. Oscar Robertson led the league in assists average at 9.7 apg (vs. 8.6 for Wilt), but played less games due to injuries. Again, having 8.6 assists per game was absolutely incredible for a center, but that is not something that he was doing in regularity, he did in once, when his scoring average dropped off steeply from his earlier years.
It is highly unlikely he could average 30ppg and 8 apg in one season nowadays, when the overall scoring was much lower than the 60’s, when he couldn’t pull it off during his days.
