Thursday afternoon’s practice featured a number of two back sets, including one with Zach Hilton in an H-Back role.  Deuce and Bush were the most popular tandem, but all of the backs were used in various combinations.  Mike Karney was an infrequent participant in today’s five on five and seven on seven drills, possibly indicating that the team plans to use a two back set as something other than simply a change of pace.  Bush played his share of WR today and looked comfortable at the position.  I’m starting to believe at least some of the hype regarding Bush and his receiving ability, as he looked natural and fluid in his movements, tracked the ball well, and caught it with his hands away from his body.  I’m not ready to declare that he would have been a top pick as a WR like some of the national media has been saying since the draft, but he does not look like a back masquerading as a receiver.  He also does not look as tall as he is listed, as Mike Karney and his purported 5′11″ frame appeared a good bit taller than Bush.  He’s looked fairly sharp carrying the ball so far and today was no exception.  The QB’s looked good as well and most balls got to their intended target.  Jamie Martin looked better today, but understandably still seems to have difficulty maintaining focus.  Mike Wallace believes the backup slot is Martin’s to lose and Todd Bouman squandered an opportunity to secure the position during Martin’s absence.  Adrian McPherson continues to be an impressive athlete and is making it difficult to draft a preliminary depth chart at QB.  I won’t be surprised if the loser of the backup spot is jettisoned to create a slot for McPherson.  AMac had the play of the day, rolling out left and juking rookie DE Rob Ninkovich out of his shows.  He consistently shows his athletic prowess, but it will be difficult for the Saints to keep him if he does not secure a QB slot.  Rookie WR Mike Hass continued his strong play, bringing a little more speed to the table than in previous outings.  He hauled in a pass at the left sideline and turned it upfield for the score.  Other WR’s of note were Joe Horn and Marques Colston.  Colston, a rookie from Hofstra, has impressive size and soft hands, but will have a difficult time making this team.  Horn has had a strong camp and seems to be connecting with Drew Brees around the endzone.  The offense seemed to have a step on the defense all practice long, save a few plays.  On a side note, the scrimmage on Saturday will be at 2 P.M. and will not be open to the public.
