The key is chemistry.
The idea that teams can just throw big name stars on a team and instantly play top notch basketball is a little far fetched. Look no further than the past USA Olympic Teams. Judging by rosters alone, it's hard to see how the US could have ever lost a game, let alone get bronze. The commitment level at the time was low, and players would skip previous games and just focus on the actual Olympic Games. Then they refocused and realized that these guys need to play together more often, and things have been good since then.
Remember that it's more important to play well later than it is to play well now. As excited everyone is to see this team fire on all cylinders, it's clearly not in the cards until they build some chemistry. Until then, people can waste all the time they want drawing old comparisons and complaining about things, but I'm holding my judgement until:
#1 The focus of the entire offense returns from injury (Nash)
#2 Until after the all-star break.
I'm a Lakers fan...BUT:
1) No I don't think Kobe > MJ
2) No I don't think LeBron sucks.
3) No I don't think it's funny to continuously make jokes about Charles Osborne.
