Kobe said he could play longer that one or two more seasons, but it's up to if he wants to. He said he could become a PG and avg 12 ast
So as is everything else with Kobe Bryant he feels it comes down to choice and whether or not he wanted to continue on with the game of basketball. With Kobe it appears he will stay as long as he has passion for the game.
One or two championships seem to be his contract extensions. Keep being Kobe..Kobe!
