stronger athletes, you’ll almost certainly win the game.
In basketball, there are a few things that make it more easy for small schools to compete:
Three point line - if you can get some great outside shooters, they can keep you in any game
Hustle - defense and rebounding are more about hustle and sound fundamentals than it is being stronger or faster than your opponent.
Team play - unselfish players who move the ball well, set up teammates, and pass up good shots for great shots is a huge factor. The warriors are great at this (doesn’t hurt they have 4 all stars either)
