My judgements(likely very wrong) based somewhat on last season and somewhat on 3 days of basketball:)
1.Durant-Looks absolutely unstoppable, his mid range jumper is nice.
2.Lebron-Looked good on both ends, didn't like how he played against the zone.
3.Rondo-I liked the driving in game 1 quite a bit.
4.Wade-Playing good ball, not sure why he/Lebron aren't shooting any 3's.
5.Rose-Took over at the end vs the Lakers.
6.Kobe-Shot too much in first two games, will be tough to stop if he plays like he did vs the Jazz.
7.Melo-Really liked that game against Boston.
8.Paul-Looked good in his first game for the Clips.
9.Love-Still the best rebounder in the league.
10.Dirk-First two games were ehh.
Honorable mentions: Howard, Ellis, Allen off the top of my head.
