Probably because they've had more settled team and/ or progress through the academy's together.
Look at Saints, they make sure the players personality is going to gel with the group and if they'll fit within it mainly by asking their playing squad.
Weve got a long way to go but hopefully now on the right track.

Commentators see Leeds defending in their own half for large stretches of games, and mistakenly assume (IMO) this is a deliberate tactic. We are in this position more often than not because of errors with ball in hand and penalties given away in defence. The simple fact is that we have far too often been unable to respect possession - and that is the root of our need to rely on longer defensive stints.

I'd have to look again at some of the early season games - for example, the HKR game that we lost. If you watch the last few games it is clear that players are moving up and there is defensive intent and even aggression at times. We wouldn't be giving so many penalties away for offside and ruck infringements if we were simply waving the opposition down the field every set!

IMO Leeds need to prioritise respecting possession, moving up the field in yardage, building pressure, and last tackle options. If the coaching team is at fault it is encouraging a style of play that often results in players trying to score from every set. This is the cause of us being on the back foot too much.

Another problem is the lack of hard running forwards to get us out of our own half when we're pegged back.

We give away offside penalties because the players are too lazy to get back on side not because they are so aggressive. I agree 100% with the errors this is a coaching issue - the inability to catch and pass properly under pressure should be an inherent skill of an elite player.

We don't appear to have clever enough players who can spot the gaps for players to run through to make yardage. Just running at the line isn't sufficient you need to find the weaknesses in the line to exploit.

Tetevano played 3 times for NZ that was during his time at the Roosters. Penrith soon offloaded him when they realised what they were getting. Leeds were negligent/desperate in paying the salary they did for a player that wasn't what they thought.

Correct, you can see that, virtually every poster on this site can see that. Unfortunately the coaching staff seem oblivious to the situation. Or maybe they choose to ignore it.

It's only in the last game I've seen us apply any kick pressure whatsoever.

Opposition kickers have routinely picked up an easy 10+ meters before putting boot to ball in every single game, with no pressure applied, allowing their kicks to be more measured/accurate.

Kick pressure is almost an automatic player response, with it being drummed into players from an early age.

To not do it suggests it was/is a definite instruction from the coach.
