The NBA games on ESPN-HD, ESPN, ESPN2, TNT, and ABC are not subject to blackout in local areas. So even though some of the non-exclusive Laker games might be showing on KCAL-9 or FOX SPORTS NET, you will still be able to watch the games on the above networks if you choose to instead.
Last week's game against the Kings was shown on ESPN-HD and KCAL-9 locally. Was able to receive both, and obviously watched the ESPN-HD feed via COX Cable (Orange County, CA).
For more information, see this page from the NBA.com web site (scroll to the bottom for the blackout rules/exclusivity stuff):
