I think the people who think Aaron is definitely done are just not trying to get their hopes up. There is plenty of reason to believe Aaron will be back this year.
A tweeter quoted the Chargers former team doc's article on Aaron's injury and said key would is COULD as in COULD return this season. Here was his reply...

True, but read the article & see plenty of precedent for 6 week return to full football. Realistic. Of course @packers may be out by then.
Nobody knows anything for sure in this world. The Chargers doc returned a RB with a broken collarbone to the field in 6 weeks. Why in the world would make anyone think it not possible for Aaron to play again? He was out 7 weeks and knocked out the Bears in Chicago. Personally, again, I think the org is severely downplaying talk of return to help Hundley and keep focus on right now not what if on Aaron. I believe Aaron will be back. I see no reason to think otherwise. Surgery speeds the healing process and he healed in 7 weeks without it last time.
Ted Thompson sits on his hands per former GM: "because they’ve had 25 fricking years of great quarterbacks. Of course it works. Try it without a special quarterback."
