Vancouver, BC: MARCH 08, 2016 Team Canada practices at BC Place stadium in Vancouver, BC Tuesday, March 8, 2016 in anticipation of the Canada Sevens rugby tournament being held this coming weekend.The decision comes on the heels of last month’s failure to qualify for the Olympics, as well as two difficult seasons on the Sevens World Series.”There’s no doubt we’re very disappointed we’re not there,” Dixon said on aconference call. “It was very attainable.””It’s about performing under pressure and performing on demand. And unfortunately we weren’t able to do that at critical moments in the season,” he said.”We hope and feel confident that with achange, we can improve those factors and get results at the times that are critical to the program,” he said.It was a tough go for Middleton, a Zimbabwe native. He was hired to replace a very popular predecessor, Geraint John, and because of his visa status, missed all of the team’s 2014 pre season, only joining the squad in the week before the 2014 Dubai Sevens. In his second season, injuries didn’t help, as many veteran players struggled with their fitness.
