I've been thinking about that. It may be to stop defenders pushing him under the ball and out of the contest. It's easy to do using hips, shoulders or forearms for one big defender, let alone two.The problem is when inside 50 he always seems to be behind 1 or 2 defenders. He can't seem to get any separation or our forward line is crowded.
I really think TL is almost the opposite of Dusty with his low centre of gravity. All Lynch's strength might be in his upper body. Notice it in ruck duels too.
He doesn't hold his ground well for a 199cm man.
