Seattle Seahawks' T.J. Duckett runs the ball as the NFL football team opened minicamp at the team practice facility in Kirkland, Wash., on Friday, May 2, 2008.

KIRKLAND, Wash. - A decade ago, T.J. Duckett and Julius Jones instantly hit it off as star high school seniors during a recruiting trip to Notre Dame.

Even though Duckett stayed home at Michigan State instead of answering the call of the Irish, he still knows Jones well. Well enough to tease him about the bulging biceps and triceps that Jones shows off each day at Seahawks minicamp. They emerge impressively from jersey sleeves so meticulously tucked it appears he hires a tailor fix them each day.

"Nice little tuck show he does," Duckett said, laughing Wednesday after another practice with his new team and teammate. "It's his gun show. I'm just trying to buy tickets."

"Great guy. I have a lot better relationship with him than you would think of another back from another school."

Or from another NFL team. Duckett, on his fourth team in four years, and Jones, the deposed Cowboys starter, have rejoined for another trip -- to Seattle to replace Shaun Alexander.

The Seahawks signed Duckett to a five-year contract in March after he spent one middling season with Detroit and one before that with Washington. When he signed, it was unclear how much the 254-pound pack of power and deceptive speed might replace Alexander. Seattle no longer needed the 2005 league MVP after two seasons of injuries and ineffectiveness.

A week later, the Seahawks signed the more accomplished Jones to a four-year contract worth almost $12 million.

After six days of minicamps, it's still unclear how Duckett fits.

Will he be the third-down back that he resembles, with shoulders rounded like Rushmore? Or will he be the versatile, every-down back he is showing he can be in these early practices?

Then again, isn't that the role Jones is here to do?

And what of Maurice Morris, who has proven while spelling Alexander for six years that he can be a slashing runner and receiver?

"You can't have enough backs," president and general manager Tim Ruskell has said more than once since he signed Duckett and Jones.

Despite Duckett's bullish appearance, he sheds his common label as if it was an overmatched tackler in the open field. Just the words "short-yardage back" make him chuckle.

"People look at me and call me that," he said. "Then I get out there and run and they say, 'OK. He's faster than we thought, he moves better than we thought.'

"That puts people in a situation where they don't know how to use you. They look at you one way, then you can do something else and they really don't know what to do."

Coach Mike Holmgren is already at that point after two weeks of work without pads or contact and emphasis on the passing game. Duckett has been catching almost everything thrown near him and shown surprising agility, just as he was advertised.

Holmgren has always preferred a single, featured back for all downs. That's what Alexander was in Seattle, and Ricky Watters, too. Dorsey Levens helped Holmgren win a Super Bowl as the lead runner in Green Bay a decade ago.

"I think you play the guy who is good at it (everything)," Holmgren said. "There are some teams that take a big, strong pile-driving guy and I guess they call him a short-yardage back. I have never done that. In fact, when I have done that it hasn't worked very well."

With Jones, Duckett, Morris and versatile, still-learning fullback Leonard Weaver, Holmgren said, "I have to see. When the pads go on, I have to see how these guys go."

Duckett looks like he goes as a linebacker, mainly because he was one. Notre Dame was the only school that recruited him as a running back out of Kalamazoo, Mich. During his freshman season at Michigan State he was a backup at outside linebacker to Julius Peterson, the Seahawks' Pro Bowl menace to quarterbacks.

By midseason, coach Nick Saban was having Duckett run the ball in short-yardage situations. By his sophomore year, Duckett was the featured back and ended up with 3,379 yards rushing. Atlanta chose him 18th overall in the 2002 draft.

His career peaked in his second NFL season with 779 yards rushing and 11 touchdowns for the Falcons. They traded him in 2006 to the Redskins. After one season Washington let him sign with Detroit. He would have liked to stay near his family again this season, but the Lions let him go, too.

He said he is motivated by the many who forget he is still in the NFL.

"Oh, definitely. You want to get back on the map," he said.

That could happen with the defending four-time NFC West champion Seahawks.

"I haven't won a Super Bowl, haven't gone to a Pro Bowl, so there is a lot of growing to do," Duckett said. "This is a great opportunity, a great organization. Out of all the other teams, I couldn't ask to be in a better spot."
