Penguins general manager Jim Rutherford hasn't solved his third-line center conundrum. Or has he? It's still early, but that's one of several questions on Rutherford’s mind entering the second week of training camp. Rutherford has been impressed by Teddy Blueger, Adam Johnson and Greg McKegg, along with potential fourth-line pivot, Jay McClement, in Pittsburgh on a “professional tryout opportunity.” At the same time, Rutherford hasn’t given up on a potential third-line center trade. The strong camps put forth thus far by those four have simply made Rutherford think. “Given the way those centermen have played early in camp, those guys are going to fight for one of those open spots,” Rutherford said Thursday. “McKegg has played well. Johnson has played well. McClement has played well. Blueger has played well. Those guys are going to make a case for us not to trade for somebody.” So the trade is off, then? Not quite. “I’m not leaning in any direction,” Rutherford said. “I’m just saying that it’s been noticed as to how hard and how well those guys have played. It’s early. We’ll continue to follow the games and how they do, but those guys have made an impression.”
