How do you know the channels who are uploading football videos either haven't received copyright claims or strikes already? If such channels are showing ads, there are three possible reasons:
1. they have been caught and the ads on the videos are from the real owners of the copyright who are earning money instead of the channel owner
2. the channel is an MCN member and the MCN they are a member of has a deal with whatever sports admin body owns the media
3. they simply haven't been caught yet.
There is no such thing as "limiting channel death". There is only preventing channel death. Once you have a channel suspended by YouTube, you are prohibited from owning, accessing or creating any other YouTube channels. Other video sites are now following suit with this same rule: Once banned, banned for Lifetime.
To give you the help you are asking for...
1. If you have already had a channel suspended by YouTube, instead of continuing with the new channel you are trying to populate, delete it and move on to another video platform. YouTube will find the new channel and suspend it with no chance of appeal.
2. If this is your first YouTube channel, cease stealing other people's content and create your own. This is the only way to survive on YouTube.
3. If you are going to another platform, search for this forum thread: The Responsibilities of An Internet Broadcaster. This pinned post contains the standard Rules of the Road which pertain to not only YouTube, but every other video platform you might publish on.
In fact you should read that post anyway as it will help you stay safe in your channel posting no matter what site you are on.
Good luck.
