AI's having a very good season, so the comparison to Kobe is hardly an insult. Still, Kobe is the more efficient scorer (AI averages 9.42 FTAPG, Kobe averages 11.15), a much better rebounder, and clearly the superior defender. The fact that he's playing with brand new teammates, playing through plantar fasciitis, and historically speaking doesn't play his best ball until after the All Star Break, should lead you to believe that he'll eventually bring his FG% back up to 45%.
This happened in 2003 as well; he shot 41% through 20 games but ended up finishing the year at 45.1%. In 2004, he shot 50%+ for three weeks following the All Star Break, and had similar stretches post-ASB in 2002 and 2003 (40 point February in 03).
