  2019 - 1 = 2018, so what wrong with WHERE sportyear = @year - 1; here?

  What is the datatype of sportyear in the table?

  If it is datetime, then your select will only bring back results where sportyear = '2019-01-01 00:00:00.000'.  Any other values in the year will be filtered out

  With @year being defined as an Integer rather than a datetime.
