"Brett and (Walls) seem like they're on the same page right away," said Packers tight ends coach Jeff Jagodzinski. "What he can bring to this football team is going to be something we haven't had here for the last few years."
Certainly, the Packers' previous tight end tandem of Mark Chmura and Keith Jackson was instrumental in the team's Super Bowl run. Even the duo of Chmura and Tyrone Davis presented opposing defenses with a formidable obstacle.
"Now we have two tight ends on the field who know what to do and how to find the seams," Jagodzinski said. "Now, which guy is the defense going to take away?"
Since Walls arrived in camp, Favre has noted the tight end's similarity to Chmura, especially as a blocker.
"The guy can play," Favre said of his friend and fellow Mississippian. "Can he help this football team if he stays healthy? Absolutely."
Admittedly, Walls' health will be a big factor in his potential impact on the Packers. A knee penchant for productivity and consistency with the Panthers, who cut him shortly after the 2002 season. He had a lackluster 19 catches for 241 yards and four touchdowns last year, and he missed 10 games over the previous two seasons after tearing his anterior-cruciate ligament.
However, the major injury factor is the great unknown with any player - young or old, banged-up or healthy.
"In this league you have to take gambles sometimes," Favre said. "Sometimes they pay off. Sometimes they don't. I just can't see why we can't take a chance on him. I've seen him burn our team so many times."
Meanwhile, Walls wants to prove that he made the right decision by putting off retirement.
"I didn't want to go out the way it (ended) with the Panthers," Walls said.
"To get an opportunity to play with a storied franchise such as Green Bay with a Hall of Fame quarterback such as Brett Favre, I could not turn that down.
"My body tells me I can do it, so let's go do it," the 6-5, 252-pound Walls said.
