The winners of the South African Conference, they had made their impact well ahead of the final and Mallett said but for a couple of missed opportunities the final could have been a lot closer than the final margin.
While not a fan of individual awards in a team game Mallett said Pablo Matera was deserving of the man of the match award.
"He has been absolutely outstanding the whole year and I had to pick a player of the season it would have to be him," he said.
Mallett felt Jaguares first five-eighths Joaquin Diaz Bonilla did not play well.
"He attacked too deep and his kicking was a bit aimless. When Domingo Miotti came on they were much better. His offensive kicks were just marvellous. And had he come on a little earlier it might have made a difference," he said.
