I think that whilst the competition is closer than it has ever been up at the top the reason for that is simply the top clubs becoming weaker rather than the lower clubs getting better. Go back 10 years and the likes of Wigan, St's, Leeds, Bulls, would walk the competition in it's current state, I'm glad that its a more even playing field, But it's an even playing field for all the wrong reasons.
Go back a decade and we had real stars in the game and some top quality imports from aus (albeit it usually at the end of their career) . We struggle to even hold onto those kind of players now.
The current wigan/saints teams wouldn't have got near the top of superleague 10 years ago.
