The 2010 Leinster Senior Football Championship Final was the last football match of the 2010 Leinster Senior Football Championship, played between Louth and Meath on 11 July 2010 in Croke Park, Dublin. Louth were appearing in their first Leinster Senior Football Championship Final in 50 years. The game is memorable for its controversial ending.
The last game of the Leinster Senior Football Championship was memorably the ending.
Given the context it was not memorably the ending of the Football Championship in general, although the ending was controversial and memorable for that reason. The system probably had trouble because I used the words in almost the same structure as the paragraph but their meaning was different.
