I am not a moron - you are. Andrew Bynum is a decent, developing player, but he is NOT there yet. He is NOT a dominating player. He also has an element of immaturity and flakiness as well. By the time he "gets it" - Bryant MAY no longer be a dominant player.
Bryant has been playing huge minutes since he was 18 or 19 years old - it is entirely possible Kobes' legs break down on him much sooner than Jordan's did, who entered the NBA at 21. That's an extra three years of wear and tear on his body. Hasn't Kobe had surgery on his knees and ankles several times in the last three or four off seasons?
Remember back in the summer, Bryant wanted to leave your beloved Lakers. He can opt still out after next year if he wants to. You must be Dazed and Confused if you think Bryant does not need his hops and explosiveness to be effective.
