The cash in needs to be epic. I think it's really going to affect Rollins going forward.
Lesnar wins at Mania>Reigns calls in a rematch at Raw>Reigns wins rematch really clean and isn't injured or anything first segment>Rollins comes out and cashes in, but sets it up for the main event, straight up match>Cena interferes for Rollins and wins him the match>Cena finally turns heel.
