I was told that the link was down so this is what you do.
What you wanna do if the link is down it just search for "Lakers" in the search and all the channels that stream the laker games will pop up.
Here is the link:

Just letting you know though you won't see any channel results until you search around the time of the laker game itself. So if the game starts at 7Pm lets let, dont search for it at like 1PM or something. Just search sometime around 7 and they will start streaming once the game starts.
