Look at every championship team since 2000, they all had PGs that can shoot, and most recently it's been the GOAT shooter.
There is no such thing as one thing you have to have unless you take it to a wide abstract like defense in general.
People did the "Look at past champions" shit every time until someone changed the way you win. You had to have a dominant center....till you didnt...then you had to win with defense and slowing it down for playoff bully ball...had a run of people wanting to copy Shaq/Kobe...get a big and a star wing...then you had to have shooters. You dont have to have anything specific.
You have to play defense. Ideally today you would have shooters...doesnt have to be specific positions though.
Wasnt 5 years ago people said jump shooting teams couldnt win...and had good evidence to suggest it.
None of this shit matters. Most teams with or without shooting arent gonna win. Ben is just an easy target to point at when the inevitable happens. Philly probably wont win the title and a bunch of teams that have points who can shoot wont win either.
Teams dont tend to win...even good ones...because winning a title is hard as hell. 2-3 teams can win for entire decades. The many losers arent all losing because of a lack of one thing....
But the rest still chase whatever that eras one thing is. Till someone shows you can win a different way. Its a copycat league. But it isnt a league that only lets you win one way.
It just looks that way to people who dont look that far into it.
76ers dont have to have shooting from the point...if they have shooting elsewhere.
