NHL Morning Links - Aug. 13

For those who can't wait for the World Junior Championships this winter -- or who just want to check in on some of their team's top prospects -- here's Corey Pronman, with an update from the Team USA WJC camp for ESPN Insider.

It was one of the classic stories that occurred during the postseason -- and could only happen in the NHL: Gregory Campbell broke his leg, but remained on the ice to help the Bruins kill a penalty against Pittsburgh. Well, the good news for Boston is that Campbell's recover is going well, and he may be available for the start of training camp in September. Elsewhere, here's a look at what to expect from Bruins netminder Tuukka Rask this season.

On the other hand, it appears that the Rangers may be without Ryan Callahan and Carl Hagelin for the start of their camp (and perhaps for the start of the season).

So will Darren Helm be in the Campbell boat or the Callahan/Hagelin boat? Here's the latest on his return from injury.

Former Leafs C Mikhail Grabovski remains an unrestricted free agent, and while there are a handful of teams that appear to have some level of interest, this report indicates that the Ducks are not one of them.

The future is wide open for Joe Thornton, Patrick Marleau and Dan Boyle, as all three have contracts that expire after 2013-14; this may mean that Logan Couture will be relied upon as a leader of the team in the future. Here's more on the Sharks' youth movement.

Canucks winger David Booth suffered an ankle injury back on March 16, and he's yet to begin skating again. Time to get concerned?

The Jets could use some additional depth in their forward ranks.

The Blackhawks are searching for someone to take over Michael Frolik's duties on the penalty kill.

Though his main priority is shutting down opposing scorers, Kings C Jarret Stoll may see a boost in his own scoring in 2013-14, if certain events come to pass.

Another angle on the new Tyler Seguin-Jamie Benn pairing in Dallas.
