First impressions on the Green Bay Packers from this weekend's rookie orientation camp were varied.   To begin with, it's awfully hard to tell what kind of football player you have when only helmets are worn and most of the on-field work is fundamental drills.  You do get a glimpse of the athleticisim of some, the size of others but we're a long ways away from determining if the draft class, undrafted free agents or longshots in for a tryout have a future in the NFL.  Head Coach Mike McCarthy thought it was very good weekend, "I was happy with the quality of work," he said. There's not questions number one pick Brian Bulaga looks the part.  The offensive tackle from Iowa looked the fittest of all the offensive lineman as he lined up exclusively at left tackle.   5th round pick Marshall Newhouse opened at left guard but also took a few reps at left tackle.  Tight end Andrew Quarless of Penn State runs fluid routes but his hands battled a few too many passes.   Safety Morgan Brunett of Georgia Tech and running back James Starks had their moments and the pair of defensive linemen taken, Mike Neal in round 2 and C.J. Wilson in the 7th were both active and energetic.   Most of the 57 players taking part were in on a tryout basis only this weekend but the Packers have apparently plucked one for a contract.  Wide receiver Shawn Gore played collegiately at Bishops University in Canada.  He was the 10th overall choice in the recent CFL draft after catching 37 passes in his senior season.  Two positions in particular drew my attention at the one practice open to the media on Friday afternoon.   Tim Masthay of Kentucky and Chris Bryan from the Australian Football League have launched the battle to become the team's punter.  Veteran Jeremy Kapinos was cut in the off-season.   Bryan is a huge bloke from down under who routinely rocketed balls off the Hutson Center ceiling, but Masthay, who was in an NFL camp last summer, was far more consistent.    The search for a third quarterback is also on after the Packers realized Brian Brohm wasn't going to cut it before he was picked off the practice squad by the Buffalo Bills last year.   Chris Pizotti, a big 6-5 kid from Harvard who was added to the practice squad late last season, and participated in the quarterback school already this spring, appears to have the inside track.   Noah Shepard, an undrafted free agent signed from South Dakota, shook off an inaccurate Friday practice and showed good athleticism and arm strength over the final two practices.  Both will get a much closer look at the organized team activities that begin in a couple of weeks.   McCarthy wrapped up the camp with a news conference Sunday afternoon and here are some of the highlights:
