I agree that Saints, Wire and Leeds all look like strong top 3 contenders. Cats, Wigan, Hudds and Cas will all be strong next season as well.
I'm concerned for the coming season because after a few seasons of fantastic recruitment, we've done virtually nothing. We're standing still in squad quality terms and, as we all know, standing still while all around us strengthen is actually going backwards in real terms.
It's not exactly doom and gloom but I see a very uneventful mid-table season which ends, in effect, the day that we're knocked out of the Challenge Cup.
