A lot of Pearce’s missed tackles are from rushing up in defense and trying to put pressure on the ball carrier coming out from deep in their own end. Barnett is the same.
You don’t often see them doing it defending their own tryline or tries coming from their decisions.
I was going to post exactly the same thing....
I often notice Pearce after a kick chase being one of the first to try and pressure the first runner with line speed - some he nails and some he hits and tends to bounce off backwards because he is hitting with pace and not technique to try and halt momentum and drive them back.
Even when he does this, he has usually slowed the ball carrier before the advantage line so that the 2nd and 3rde tacklers can drop them at or before the Advantage line.
Whilst his age is starting to show that he is not the 80 minute player he used to be and he is not perfect, I've never considered him a defensive liability to the team and I'd go as far as to say his defence is one of his strengths compared to most other half backs in the NRL.
And he certainly comes from good stock on the defensive front too...his dad was one of the best pound for pound defenders I've seen and, like his son, had a big motor to do it all day.
