Carolina defensive end Julius Peppers is the premier player in what is an unspectacular

class of NFL free agents.

Peppers, who just turned 30, is expected to break the bank as the NFL begins its free-agent

shopping season. Free agency began at 12:01 a.m. today. Peppers is a five-time Pro Bowler who

has made 25 sacks the past two years. Bidding is expected to be intense for him.

However, the fact the NFL is in the final year of its collective bargaining agreement with the

players union has dramatically changed the free-agent landscape. Because there is no salary

cap this year, players must have six years of NFL experience to become free agents instead of

the usual four. That has turned roughly 200 players who would have been unrestricted free

agents into restricted free agents. In most cases, a team has to pay draft-pick compensation

to sign a restricted free agent.

"In the past, we would have seen a lot more numbers out there," Atlanta General Manager Thomas

Dimitroff said at last week's NFL Scouting Combine. "We would have been contemplating, when

March 5th came around, if we were going to jump in there and we'd be really busy during that

time. I sense that we are a lot more focused, seemingly this year on draft preparation."

About 240 players are unrestricted free agents, but at least two-thirds of them are 30 or

older. Players over 30 tend to linger on the market longer.

There is likely to be a flurry of activity in the first days of free agency but then a lot of

waiting around for many veteran players.

After Peppers, some of the top players available include Houston cornerback Dunta Robinson,

who is 28; Arizona linebacker Karlos Dansby, 28; Indianapolis linebacker Gary Brackett, 29;

and Green Bay defensive end Aaron Kampman, 30.

Older stars who are available include Chargers back LaDainian Tomlinson, ex-Bills receiver

Terrell Owens, Saints safety Darren Sharper and defensive end Charles Grant, and Jets back

Thomas Jones. Miami linebacker Joey Porter, 32, is expected to be cut by the weekend.

More intriguing are the players on the restricted list. No one is quite sure how much bidding

there will be on those players, given the fact teams covet their draft choices. The top

restricted free agents include Broncos receiver Brandon Marshall, Broncos linebacker Elvis

Dumervil and Chargers receiver Vincent Jackson.

In another uncapped-year rule change, the teams that advanced to the final four in the

playoffs can't sign a free-agent unless they lose a player. The other four teams that made the

final eight have significant limitations on their signing ability, as well.
