REPORT DATES: Rookies July 29th, Veterans July 29th SITE: Hofstra University, Hempstead, NY CAMP OBJECTIVES: New offensive coordinator Mike Heimerdinger steps into the role formerly filled by the deposed Paul Hackett, and inherits a few concerns. First, he likely won't have the full services of quarterback Chad Pennington, who is coming off shoulder surgery. Heimerdinger must make sure new backup Jay Fiedler (Dolphins) is ready to play in case of another Pennington injury, and also needs to get Laveranues Coles (Redskins) up to speed in the receiving game. With Curtis Martin nearing his sell-by date and LaMont Jordan now a Raider, the Jets need Derrick Blaylock (Chiefs) to be ready at running back. On the line, tight end Doug Jolley (Raiders) and second-year player Adrian Jones must be ready to occupy starting positions. The defensive question marks are fewer, though Lance Legree must prove he is capable for taking over for departed nose tackle Jason Ferguson (Cowboys) and a still-sketchy cornerback situation needs to be sorted out. In light of the team's kicking woes in the 2004 postseason, second-round draft pick Mike Nugent (Ohio State) must put Herman Edwards' mind at ease with some early consistency.
