As impressive as it'd be for a myriad of reasons, should one more championship really be the determining factor, when we've got more than enough information to formulate opinions to begin with? I already have him top five, so one more championship isn't really going to change anything.
I said the same with Nowitzki last season. I had him as the fifth best PF of all time before winning a championship and I have him fifth after winning a championship, because he didn't suddenly become any greater. And even though I don't foresee Bryant winning a sixth, let's just say for a second he does. I'm still putting him behind Duncan, O'Neal, Olajuwon, etc. They were all superior players, no matter how many times he get's dragged to a ring by having the most dominant player/combination of bigs on his team.
