Brad Fittler will be stressing the importance of discipline in Wednesday's State of Origin opener in Melbourne, with the Blues conceding many more penalties than Queensland late in the tackle count over the past 10 years.
Since 2008 the Blues have given away 19 penalties on the last tackle, compared to Queensland's 10, while also conceding 17 penalties on the fifth tackle compared to the Maroons' 14 in that time.
NSW are also guilty of giving away more penalties at the wrong time, with 22 inside the final 10 minutes of a game while the Maroon have conceded 17.
Those figures are in line with the overall penalty count over the past decade, which is in favour of the northerners 169-155.
However, the Maroons have conceded more penalties on their goal line, with 18 infringements inside their own 10-metre zone, compared to the Blues' 15.
Out of the players who will line up in 2018, the Blues' biggest offender is James Maloney, who has given away 10 penalties to be the state's second overall offender behind former captain Paul Gallen's 14 indiscretions.
The three Queenslanders who have offended the most over the past decade - Cameron Smith, Nate Myles and Johnathan Thurston - are no longer in the team.
