As the Pittsburgh Steelers attempt to pump up a so-so special teams unit, they’ll be using one of their first-day picks for the punt-return team.

But receiver Limas Sweed, a second-round pick last month, won’t be returning punts.  He’ll be trying to block them.

“Coach [Bob Ligashesky] said he likes me coming off the edge, using my speed to block punts,” Sweed said Wednesday.  ”I never did special teams in my life until I came here, and I actually like it.”

Though some teams don’t like to expose key players to injury on special teams, the use of second-stringers necessarily creates (at times) a second-string result.  So why not use the best athletes on the team to assist with these often overlooked phases of the game?
