It is really easy to follow NCAA March Madness but if trying to follow the playoffs of another sport like the NHL or NBA is difficult. The major websites like ESPN, SI, CBS Sports, or even NHL.com and NBA.com tend to only show you the most recent games of the match-ups. You need to do a lot of work to visual the bracket and how the teams are doing.
I found and like the following sister sites. They have them for other events but these are good ones. They do not update in real-time, rather nightly, but you can see how the series are progressing. Just a quick shout-out. Well done.
