The 6-foot-6, 300-pound Barton was a seventh-round draft pick by the Chicago Bears in 2008 but has played in only one NFL game. Barton has also had stints with San Francisco, Miami and Cincinnati. He did not see any action in 2009.
NOTE: The wholesale Panthers jersey have waived offensive tackle Jason Capizzi and claimed offensive tackle Kirk Barton off waivers from Denver.
"We still work on it every day. We are trying to get to the point where we can consistently make plays in the run game. I would love to say that we can run against any front on any defense, (but) that's not entirely true."As for the team's running game, which has been without right tackle Jeff Otah and running back Jonathan Stewart in the preseason, Davidson said, "I don't think anybody would sit here and say that we're happy with where we are in the run game.
"Mac(kenzy) has a leg up on the competition, but he's not a shoe-in," Davidson said.
The same, he said, goes for the right guard spot, which remains up for grabs between Macenzy Bernadeau, Geoff Schwartz and Duke Robinson.
"Dwayne Jarrett has actually done a nice job in this camp, and Brandon LaFell has come in here and taken the bull by the horns, if you will, in trying to earn that job," Davidson said. "I would love to stand here and tell you that one of those guys has done it, but it's hard for me to say that it's even one of those two guys right now, because Wallace Wright has shown he's capable of being that guy and Kenny Moore has shown he's capable of being that guy. So right now it's still very much a competition."
The cheap Panthers jersey aren't expected to bring in a wide receiver from outside the organization to help.
LaFell and Jarrett are viewed as the frontrunners to win the starting spot opposite Smith, but Davidson said nobody can say they've won the job.
The Panthers overhauled their receiving corps during the offseason, adding Brandon LaFell and Armanti Edwards in the third round of the NFL draft while signing Wallace Wright in free agency. They also continue to rave about Dwayne Jarrett's progress and believe the perennially disappointing former second-round draft pick could be a step closer to winning the No. 2 spot.
Outside of Steve Smith, who has yet to play in the preseason, the Panthers had little else in the passing game in 2009, and quarterback Jake Delhomme struggled all year with turnovers, often trying to force the ball into Smith's hands.
That's something the Panthers struggled with last season.
"I would say this: we're always going to be about finding balance on offense," Davidson said. "The major push for is us when a defense is making us throw it, we have to be efficient when they are doing that to us."
He still views the running game as the strength of this team — and with DeAngelo Williams and Jonathan Stewart jerseyrunning behind a veteran line, why not? — but said making plays in the passing game when needed will be key to the team's overall success on offense.
When asked if he thinks the Panthers will throw more often in 2010, he simply said, "No."
Davidson said there's also a misconception that the Panthers will be throwing the ball more this season after spending three days of OTAs working on the passing game.
"As far as the week-to-week game planning, that is the tweaking we haven't done. It's the same plays we'll end up using in the regular season. I'm not going to say that the excuse is going out and designing the right plays. We have enough plays in there to make them, but we got to get to the point where we make them."
"We have plays in. There's no excuse for it, quite honestly," Davidson said. "There are plays that we have in — and we have to be able to make plays. That's something where part of it is coaching and part of it is playing. We have to make sure we get out there and get better.
Now, he said it's a matter of going out and doing it.
Davidson said the team has installed about 70 percent of its offensive playbook, which he said is more than enough to give the players a chance to make plays in the preseason.
"But I want to make sure that we all understand that there is a sense of urgency in getting better at it. And I do think we need to do that."
"No," said Davidson. "I'm not concerned with it. I think we have a good focus on it. We have time before I start getting concerned about it here.
The Carolina Panthers jersey have only completed 42 percent of their passes so far this preseason, and their quarterbacks have been sacked a combined 11 times, but offensive coordinator Jeff Davidson isn't fretting over the team's passing game.
