Jackson, one of Buffalo's veteran leaders, has sensed a positive difference.
"An extra roster spot is always a good thing," Whaley said, when asked if Byrd could be exempted for the Bills opener against New England on Sept. 8.
The Bills approached the NFL for an exemption a day after Byrd signed his one-year, $6.9 million franchise tender. General manager Doug Whaley told The Associated Press he had not ruled out having the exemption extend into the regular season.
That request was denied because the NFL generally limits exemptions to two games. Buffalo plays at Washington on Saturday, and closes the preseason hosting Detroit on Aug. 29.
"We've got to continue to get better," Marrone said. "We're still a work in progress and we're not where we need to be."
Byrd,Cheap MLB Jerseys Store, however, must still pass a physical.
"We all know what type of player he is," Marrone said. "I don't think it's probably as big of an issue as maybe people might make it out to be. ... I'm sure that he was in communication with a lot of his teammates. And I think that that helps the transition when he comes back in knowing what we're trying to accomplish."
Whaley described the request as "standard procedure,Authentic NBA T-shirts Canada," when involving a player such as Byrd, who has missed nearly the entire offseason because he was unsigned.

In granting the Buffalo Bills' request to have the newly re-signed player not count on their roster, the league limited the exemption only through the team's final two preseason games.
Though Byrd is now under contract, he is not expected to report to the team until later this week.
On offense, Buffalo's young receivers have played well. Rookie speedster Marquise Goodwin was among the team's best overall performers, making big plays down the field.
Marrone was pleased with camp, but stressed there's more work to be done.
The ruling, announced Wednesday, becomes the next step in clearing the way for the two-time Pro Bowl safety to open the season on the active roster.
Goodwin, along with rookie second-round pick Robert Woods, are being counted upon to take pressure off returning starter Stevie Johnson this season.
PITTSFORD, N.Y. (AP) ? The NFL isn't going to stand in safety Jairus Byrd's way to open the regular season.
The first-round draft pick is expected to miss the rest of the preseason, but has not been ruled out for the opener.
The exemption granted by the NFL begins Tuesday,Eduardo Salvio Jersey, when teams are required to cut their rosters to 75 players.
The Bills wrapped up camp with a 90-minute practice,Air Max 1 Scontate.
Byrd would not have been paid if he wasn't on the active roster for the first week of the season.
Manuel's injury came less than a week after veteran Kevin Kolb returned from a left knee injury. Kolb was hurt Aug. 3, when he slipped on a wet rubber mat between practice fields.
He's missed all of the team's offseason workouts,2018 World Cup Russia Jerseys, and all of training camp after the Bills held their final practice in suburban Rochester on Wednesday.
The mood was light and upbeat. Receivers switched jerseys, running backs played hot potato after practice, and there were several pranks pulled.
"The whole team, everybody's really buying into the systems and everything that the coaching staff is putting in," Jackson said. "Tremendous energy out of our coaching staff and excitement. I haven't seen guys this excited for a long time."
A video of running back Fred Jackson dunking a miniature basketball over Marrone in the team's locker became popular after being released on the Internet.
Buffalo's new-look defense tops the list of positives for the Bills, who now return to their Orchard Park headquarters. Throughout camp, the defenders frequently flustered the offense with a variety of blitzes.
It's something that continued to illustrate a growing bond between the players and the rookie coach.
Injuries at quarterback were the most disappointing aspect of camp. Rookie EJ Manuel appeared well on his way toward earning the starting job until injuring his left knee in a 20-16 win over Minnesota on Friday.
Earlier in the day, coach Doug Marrone was encouraged by Byrd's signing, and didn't believe it would take long for the safety to grasp the defense installed by new coordinator Mike Pettine.
It does not extend past Aug. 31, when teams have to establish their 53-player rosters.
