Griffiths said: “That’s where you’ve got to get to – to be competitive for the whole game. We need to stay in this league and that’s what we’ve got to be doing.
“We’ve got to be in the mix and we can learn a lot from our performance in both the first and second half.”
Crusaders were level at 6-6 at half time, but conceded 30 unanswered points in the second half.
Griffiths added: “We can be enthused by our performance but we’re disappointed with some bits, particularly the game management and our decision making at times.”
