The difference is the NFL has more natural stoppages of play such as change of possession. NCAA games are about TV timeouts. Naturally the worse is the end of the game where timeouts are called seemingly after each basket. With so many timeouts in college baskets you really never have to take out your best players for a blow. Hockey and soccer are the least disruptive sports for stoppages.
Basketball is natural.
Under 16, under 12, under 8, under 4, and halftime.
Repeat the same process for the second half.
And commercials when a time out is called. Just like football.
And for the end of the game.
Its the same in football.
You have the 2 min warning and a lot of timeouts near the end on a close game.
