And Flood was quick to praise the work and effort of his team-mates.
"The result was massive," said Flood. "Coming here with the performance that we did was a credit to how the guys worked during the week.
"It was an arduous week. We'd had a week off so it was a shock to the system coming back but it was well worth it.
"Everyone worked really hard. It was a real squad effort."
Flood said there was still room for improvement, despite Tigers recording their biggest Premiership win at Franklin's Gardens.
"I think we have still got 10 or 15 per cent to go," he said. "There were times when we maybe slipped off tackles, times when we made mistakes.
"Certainly there is room for improvement. And coming into the business end of the season it is so important for us to tighten those areas up because if we go into a semi-final and make a couple of mistakes that could be it gone."
