Mark Jackson grew up playing Gaelic football. He's taking a shot at the American kind in Pittsburgh

Mark Jackson does not look out of place. Standing inside the Pittsburgh Steelers practice facility on Friday, Jackson's yellow No. 2 blends in with the other 42 players trying to catch head coach Mike Tomlin's attention during the team's rookie minicamp. At 6-foot-1 and a solid 214 pounds, Jackson practically towers over Caleb Shudak, the other kicker brought in for a look. Things change, however, when Jackson starts to talk.
