Football's version could reside in Green Bay. Although the atmosphere was purposely subdued because it was an indoctrination, the Packers' rookie orientation camp May 2-4 gave the coaches a taste of the nastiness possessed by offensive linemen Breno Giacomini and Josh Sitton.
"It's whistle to whistle and, sometimes, beyond the whistle," Giacomini said of his ornery disposition on the field. "That's just having fun. I'm going to have fun playing as an offensive lineman. That's how I learned to play offensive lineman, so I don't know a different way. It's just fun."
Giacomini, though, was reprimanded last year at Louisville after making an obscene gesture toward fans of Kentucky before the teams' rivalry game. He chalked that up as an isolated incident and has moved on from it, but the fifth-round draft pick isn't apologizing for his feisty approach to playing football.
Ditto for Sitton, who was taken a round ahead of Giacomini out of Central Florida.
Packers head coach Mike McCarthy was encouraged by the fire he saw from the two rookies in an otherwise relaxed practice setting involving only about 45 players.
"I really like their disposition, and they're both very aggressive," McCarthy said. "They have the right attitude. Athletically, they're really what we thought they were."
Of the pair, the 6-foot-3, 319-pound Sitton is in a better position to vie for a starting job this year already. The Packers are unsettled at both guard spots. Sitton lined up mostly at right guard in the rookie camp but also has experience at left guard and right tackle, his primary starting position the previous three years.
"The versatility is huge. You've got to be able to play more than one position at this level," Sitton said.
Giacomini is a possible successor to one of the team's veteran tackles, Mark Tauscher on the right side and Chad Clifton on the left. The 6-7, 303-pound Giacomini is a converted tight end who started at right tackle for Louisville last season.
