You don't need to average anything to get a starting spot, you just have to be popular and have people vote for you. Starting an ASG in most leagues is about popularity over performance in most cases.
I don't see Gasol making it yet this year.
If the suns continue to have a strong record Amare gets in, Oden might get in because of his improved play (plus the NBA wants him to be a star I'm sure, he was a #1 pick), I think from a crap team, unless he's categorized as a PF, that Kaman might deserve it over Gasol as well...
