The two sports, hockey and lacrosse have many similarities and differences. The similarities are they both have gear and referees. The importance of gear is to protect you from sticks and pucks. The importance of referees is to make the game as fair as they can.
They play on different surfaces. Hockey plays on ice and lacrosse plays on a field. Lacrosse has ten players and hockey has 6 player. Lacrosse has a deeper net than hockey nets. Hockey has boards and lacrosse has none. So I think hockey and lacrosse are more similar than different.
