Absolutely ask for feedback. I am waiting to see how the starting lineups shake out before giving my opinions publicly on where the teams stand in my eyes. I will give anyone feedback via PM and my guess is the other panelist will as well.
Also, here are a couple of good sites
http://www.basketball-reference.com/Basketball-reference is great for looking up All-Star teams, All-NBA teams, All-Defense teams for any year and also checking out stats of every player. In the player index area they have fabulous tools for comparing players, how players fared against each other and how players shoot from specific areas of the floor.
http://www.nba.com/history/players/http://www.nba.com/encyclopedia/These sites at nba.com are awesome as they give you write ups about the greatest players in NBA history, the greatest teams and tons of other info you won't find in many places.
I know there are lots of others.
