I like counterpunch boxing news. Kurt can always articulate his arguments very well. Straight to business. He is good.
Boxing Life and Boxing Gems are good for analysing fights and fighters. Hardline Boxing Talk can be pretty good as well. He's a bit of a grump though lol
I don't really follow any of them closely anymore. I watch some of them some of the time. Chris Andre Boxing is pretty good.
And Rummy's Corner of course I also watch Carl Froch's channel on occasion just because I find it amusing when he refers to himself as The Cobra
The OP included Counterpunch Boxing News. It's been my main YT boxing channel the past few years. Kurt is about as unbiased as any channel. For a while he succumbed to the anti Fury crowd, I suppose to get views. But he seems to be over that. CBN uses the quantity over quality method pumping out multiple vids per day. I watch others, for example: iFL TV, DAZN, and of course Rummy's Corner.
