Rio Ferdinand from ManU should have been on the list no questions asked.

Um exactly how is Peter King, one of the GREAT and FIRST journalists to actively use twitter AND has over 500K followers, NOT on your Twitter 100? Are you guys insane?

How is SportsBizMiss not on ther?? No one else covers the business of college sports in such detail!

No Fake Bo Pelini?? @FauxPelini. A must-follow.

None of the guys from The Basketball Jones? or is TBJ too much of a competitor to include?

Um, no cycling accounts? Have you forgotten about a certain Lance Armstrong w/ 2.9Million followers?

Nascar Hall of Fame driver Darrell Waltrip (@Allwaltrip) Hey the Guy in his 60's and he one of the top drivers of all time. He jumped into Social media with both feet. He's got Twitter, Facebook and a weekly YouTube (Allwaltrip)

former NHLer Pavol Demitra @PavolDemitra is hilarious (though inappropriate and NOT political correct) and also offers great dressing room/behind the scenes insight without having to worry about an nhl team filter. also Jay Onrait @JayOnrait is TSN's most entertaning tweeter

Bill Walton is Twitter Gold!

For complete NBA basketball, @InsideHoops absolutely belongs on your list. Every NBA freak on the planet follows it. Almost every NBA beat writer. Almost every major radio host. And the majority of actual NBA players

For soccer I like to follow @sidlowe (la liga). You'd get way more tennis news, not to mention fun from following @FortyDeuceTwits (WTA) or @JamesLaRosa (ATP) than Matt Cronin.

No ChrisWarcraft (Chris Kluwe). For shame CNNSI.. for shame

Wake me up when one of your 100 clowns gives away a car on Twitter. Until then they're looking up @RioFerdy5 and his 1.3 million followers. It's a #movement. #oof

You can't go wrong following @ColtMcCoy ..... Football, Hunting,Football, BBQ, Football, and Texas!

Formula 1 driver Rubens Barrichello. I guess because he tweets to his home country fans the most in Portuguese he's easy to overlook, probably just like the million followers he has.

Seriously? How could you leave Tony Hawk off this list? He's one of the most followed people on Twitter and does international Twitter hunts and posts more interesting stuff in a week than most of these people do all year. But you put Kelly Slater on there. #outoftouch

HOW can there be a sports twitter list without @DownGoesBrown?????? The most hilarious blogger in hockey!
also just wait... @stache16 is new to twitter but he will become a household name lol
he is hilarious, smart and just nice...

Very good list, however with the omission of Keith Law and Deadspin it isn't perfect. Both feeds are informative and usually hilarious.

Marvin Austin has the most talked about twitter account in the sports world for the last year, and he doesn't get a sniff on the list. @anchormanaustin is still trying to sink the Tar Heels with his tweets.
