Functions in WHERE

You want to know which players from the 2017-2018 NBA season went to college in Louisiana. You ask a friend to make the query for you. It looks like he overcomplicated the WHERE filter condition by unnecessarily applying string functions and, also, it does not give you precisely what you want because he forgot how to spell Louisiana. You will simplify his query to return exactly what you require.
