The Tigers get a chance to atone from what has become a bad run in their traditional Thursday night round one clash against Carlton this week, having not beaten the Blues on the occasion since 2008.
Cotchin said the team has worked on making amends.
"I think last year we just had a patch where we mentally let ourselves down," he said.
"We've got things in place that hopefully we can stop those sort of run ons from opposition teams because it is a game of momentum."
