Quite frankly I think that the Kings have it easier against the Mavs, than the Lakers have it against the Spurs. The lakers and spurs will beat the snot out of eachother, while many analysts think the Kings will manage to beat the Mavs in a less physially demanding fashion.
Also if you look at the regular season record, the Spurs went 4-0 against the Lakers. While the reg season doesn\'t mean much, it does show that the Spurs match up well against the Lake Show.
One thing is for sure, both series will be a joy to watch. To quote the Kings announcer Grant Napear, "If you don\'t like that, you don\'t like NBA basketball"
