Changes are likely coming for the Chicago Blackhawks in the not-so-distant future.

Don't worry the core will likely stay intact. There isn't expected to be much turnover in the team's wingers and defensemen. Wings Bryan Bickell Marian Hossa Patrick Kane Brandon Saad and Patrick Sharp and defensemen Duncan Keith Nick Leddy Johnny Oduya Michal Rozsival and Brent Seabrook are all signed through at least the 2014-2015 season.

Where change may occur though is at center. Aside from Jonathan Toews there's plenty of uncertainty over which players will fill the team's centermen roles in the future.

Some center changes will arrive next season. Most notably the second-line center is up for grabs again.

Brandon Pirri Andrew Shaw Marcus Kruger and Michal Handzus all of whom have played center in the past were thought to be the logical choices for the spot. But Blackhawks coach Joel Quenneville did away with that assumption when he recently said Saad who has mostly played left wing in his career will be given first crack at the second-line center opening.

"[Saad] is probably the guy we're thinking maybe grab that spot would be an option" Quenneville said during the Blackhawks convention. "It's something we talked about as a staff late in the year. It's something going into the season we could be exploring."

The 20-year-old Saad has proven he can be a top-6 forward. He's strong with the puck and has a knack for producing offensively. He also earned some time on the penalty kill as last season progressed. But he's not a sure thing at center where distributing the puck and winning faceoffs are often essential skills. He may be able to fill the job but training camp will be key for him.

If Saad does work out as the second-line center the chips likely will fall in one way. Shaw is likely to remain as the third-line center. As long as he's being smart about his aggressiveness he provides enough offense and defense to be a perfect fit for that third line. Handzus would likely be the fourth-line centerman. Kruger has played the wing in the past so he'd probably move there. Pirri has the offensive skills to be a winger and may have to settle for that this season. He could also fill in for Handzus when Handzus needs time off.
