SELECT TOP 2 * FROM Table ORDER BY Points DESC

Is what your Prof wants to see right about now

what if you have 10 teams with 5 points?

You don't like my TOP 2?

TOP or ROW_NUMBER() won't work if you have more than one team in lowest/second lowest
Use visakh16's answer with DENSE_RANK instead:

SELECT Team_Name, Played, Won, Drawn, Lost, Points
FROM
(
SELECT *,DENSE_RANK() OVER (ORDER BY Points) AS Rn
FROM Table
)t
WHERE Rn <=2

what about TOP 2 WITH TIES?
