If you were unaware that SB Nation had created a YouTube channel then you are missing out. It offers a variety of new material everyday covering a huge number of topics. Some are serious and investigative like Amy K. Nelson with her "Full Nelson". Bomani Jones does great commentary in "Bomani and Jones". EDSBS produces a college football centered show entitled "ShutdownFullback". There are also plenty of humorous pieces that cover sports and the internet gags.
There was plenty of coverage and analysis last weekend of the NFL Draft.
I'd never really seen the benefits of subscribing to a channel on YouTube until recently. There is a ton of new content that SB Nation puts out every day. Now you can see all the latest videos as soon as they are released.
Here is one example of a piece on the NFL Draft I enjoyed.
