I think you're making an unfair generalisation there with Lids, Rainsey and Simmo.
Lids had 2nd year blues last for sure, but his working into some good form.
Rainsey is struggling a bit a la Lids last year, but it's just a thing I reckon he will work out of (the faster he gets moved onto a wing the better).
And with Simmo you can't criticise him for a being a one year wonder, he's missed pretty much the whole preseason and can't be judged.
