The NSW Waratahs have been put on notice about displaying better body language, as they prepare for a brutal Super Rugby battle against old rivals Queensland.
Some players were caught sucking in deep breaths and on their haunches in last week's fast-paced game against the Chiefs.
That was noticed by television commentators and also by Tahs' forwards coach Simon Cron.
"A few hands on knees, which is a cardinal sin for Cronny, I would hazard a guess that not many guys will be on their haunches this week," Waratahs flanker Michael Wells said.
"I think it's something that we're going to work on ourselves, the body language.
"It's not an excuse to cut corners or go a bit easier just because you're tired.
"If your life's on the line, which is how we should be playing, you've got to make the effort.
"I think we've rectified that. A few blokes have been put on notice and we'll be better this week."
Cron has no qualms at game reviews on a Monday morning about identifying perpetrators of negative body language.
"Reviews are a pretty sobering moment when blokes see Cronny pull up clips and they are on their haunches and sucking in the deep ones," Wells said.
"Our on-field leaders are pretty strong about body language, Hoops (captain Michael Hooper) particularly.
"He doesn't stop, so he expects the same from the other 14 guys on the field."
The conference-leading Waratahs are bracing for a rugged clash with a Reds side Wells said loved to battle and grind.
"It's going to be won in the trenches, particularly in the forwards, and if we aim up we'll put ourselves in good stead," Wells said.
"It's going to be won in the head particularly, as well as physically.
"It's a mental battle in yourself getting up, and if you get in front of a guy, there's no excuse to miss the tackle.
"That's what we're really going to pride ourselves on this week, we're going to measure ourselves on our defence."
Wells dismissed the Tahs eight-match winning run against the Reds as irrelevant, but felt NSW controlled their playoff fate with all of their four remaining games against Australian conference rivals.
