I think it's time to mention the first US handball blog I know of. It's by the former US National Team circle runner John Ryan. I met John I think at the 2001 National Championships and got to know him as a very reliable and experienced circle, positive team-mate and a sharp thinker with always the best interest of the sport in focus.
With that mix of talent, character and brains, is it a wonder his blog is very well worth reading? Go there now and check it out:
