Omar Kahn, Kevin Colbert and Art Rooney II are not resting on their laurels following Steelers OTAs.

They closed last week by signing 7th and 4th round picks Doug Worthington and Thaddus Gibbons and they opened this week by signing third round pick Emmanuel Sanders, whom they selected in the 2010 NFL Draft.

Sanders will enter camp with an eye toward wresting the third wide receiver slot and his main competition aims to be Antwaan Randle El, who rejoined the team this off season after spending the past four seasons with the Washington Redskins.

Emmanuel Sanders selection caught some draft veterans by surprise, as he is a little on the small size, but he impressed Steelers coaches with his hustle and work ethic.

Victory for Twitter

Those who want to stay up to date with the latest in Steelers news should stay tuned to Twitter, as that is where Sanders broke the news himself.

Yours truly discovered the news on Behind the Steel Curtain, and verified it on Steelers Depot, which linked to Sanders Twitter feed.

The truly interesting thing about this is that Twitter allowed these two fan-based sites to beat the Pros to the punch. As of 8:15 Eastern on Monday the 14th, neither the Post-Gazette, the Tribune Review, nor ESPN.com were reporting the news. (Cue Aaron Copeland’s “Fanfare for the Common Man.”)
