Seriously Bretts, you spout "much better than with Cooper and Groves" and what you've put up is Matt frickin' Smith and 'surely there's a better import around'.
Typically the next step on that path is "I'm sure there's better, but it's not my job to know who the actual options are." Then, when based on knowledge of players, info from team-mates, budget considerations and the like, the people whose job it is put forward their selection, you disagree and cite general armchair consensus as support.
Paul, posting above, is (AFAIK) based in Melbourne and spoke favourably of the likely candidate in Groves - that counts more with me than Adelaide-based people going on stats. I asked Boti for his opinion of Groves as a potential 36er and he would like to see it happen. Goorjian would've waited for Cortez to return from injury had time been on his side and he didn't have to qualify Smith for the finals so Cowan's money wasn't wasted for nothing. I'd guess that Burston, Herbert and Ballinger haven't raised an objection either.
Worthington will be up against Ballinger and Holmes, not an import SF. Can't think of many other teams that are going to be better equipped to handle him - at PF, teams will have Redhage, Ronaldson, Forman, Gruber, Boucher, Rychart, Hinder, Davidson, Wagstaff and others who are going to be at a similar level.
The SFs around the league are hardly monsters for Hill/Holmes/Herbert to deal with either - Tovey, Williamson, Boodnikoff, Crawford, Saville, Thomas, Greer - some good players, but not heavyweights. White (Cats) and Mackinnon will be strong it's not like Grizzard or the typical SF imports are going to be able to throw them around either.
And every team is going to be weakened by the loss of a key player. Take Rogers out of Perth and what do they do? Take Saville out of Wollongong, an import C out of NZ, Anstey from Melbourne, etc - they'll all have as much trouble covering for those.
At this point, I think Burston may be the second best big in the league. The Ballinger/Holmes combination is probably the best (or close to it) at PF. If Groves is our man, then Gilchrist with Groves as back-up may be the best PG combo (I think Bruton is very, very good though). Groves at SG backed by Ng, Herbert and Hill is quality (Penney easily the best there).
That leaves SF. Get a SF import, and you're weaker at SG. Every team is going to have one place where they couldn't budget (money or points) a superstar. Melbourne have Crosswell as starting PG. Gold Coast might have Vanderjagt in the middle. Wollongong will have one of Tragardh or Vanderjagt. Perth have Rogers at C and then the Martin/Robbins duo at PG. And so on.
At SF, an improving Hill and Holmes will be fine.
