Blackhawks done making moves?

While not completely closing the door to his offseason spending spree, Chicago Blackhawks general manager Stan Bowman intimated he was done shopping, including for a new center.

"People always want to say Patrick Sharp isn't a center but he's done it the last couple of years," Bowman said on the final day of prospect's camp. "I don't know what he has to do to prove he can play center. He's a good winger too but we won a Stanley Cup with Patrick playing in the middle. That's always an option."

The Hawks ended last season thin at center and could conceivably start the next one in the same position. There are no indications they plan to bring back Ryan Johnson, leaving Jonathan Toews and Dave Bolland as the returning "stalwarts" at that position. Young Swede Marcus Kruger has a job there as well.

Bowman continues to focus on his remaining unsigned restricted free agents, Chris Campoli and Michael Frolik. Campoli is set to go to arbitration on August 3.

"We're still negotiating," Bowman said. "It's an on-going thing. Back and forth between the agents and myself. No news really to report. We're not there yet but we're still talking which is a good sign. It's hard to handicap at this point."

Winger Viktor Stalberg signed a two-year deal on Sunday.

"It's a fair contract and it gives him an opportunity to grow his game over the next couple seasons," Bowman said.

Coach Joel Quenneville also attended the final day of camp, speaking for the first time since the Hawks signed five free agents on July 1, including supreme agitator Dan Carcillo.

"I think he has more versatility than being a one-dimensional tough guy," Quenneville said. "There is some skill to his game. He can play with some top guys as well. You can move him up in certain situations. That edge he can bring is something we were looking for."

Quenneville is happy with the new additions, which bring some leadership, size and toughness to the Hawks.

"We're better equipped going forward for all our needs," he said. "We have a great core and the guys we brought in this year really complement that core. Their experience and leadership are complimentary to make us a better team. We fulfilled our needs."

Quenneville said John Scott would focus on defense as training camp opened, which means the Hawks could have eight defensemen looking for ice time when all are healthy.

"That's a healthy situation you can be in," Quenneville said. "You can never have enough defensemen. You'd like to have nine or 10 deep with some experience if you could."

One player who could be considered an "X" factor is forward Rostislav Olesz. He was acquired when the Hawks traded Brian Campbell to Florida last month. He missed the last part of the season with a knee injury and remains unproven as a 25-year-old with parts of four seasons in the NHL.

"He's a player that needs a fresh start," Bowman said. "We haven't even seen him here in a training camp yet. He has some versatility to his game. He has a lot of ability. The only way we know that is when you get him on the ice."

Don't expect a surprise addition to the NHL roster coming from this year's prospect's camp. Whereas defenseman Nick Leddy made a big impact last season after attending the 2010 camp, this year is different.

"This was less of an evaluation camp and more of a development camp," Bowman explained. "It's why we kept the numbers down and (had) only two scrimmages. ... The focus of the camp wasn't so much in trying to uncover the next Blackhawk."
