The NBA has better flow because every team is full of elite offensive players.
College basketball will never be the NBA.
That is partially true, but officiating and 11 seconds slower on each clock has its impacts. One and one free throws often rewarding fouling is another reason.
Every major level of basketball including womens ball has a faster shot clock than 35 seconds. If it's so great we should be arguing to extend the shot clock to 45 seconds and get these other leagues up to at least 35.
If you're a fan of a team that is winning by grinding lots of clock you enjoy it. That's a small % of college basketball viewership though.
