They'll definitely sign Lauzon, I wouldn't rule out him turning pro next year at all. Sure, he had a bad year this year, but he's probably a pro ready player. His skating and defense are definitely both professional ready, so if they're not worried about his offensive totals, I could see the Penguins wanting him in the AHL next year.
It depends with Hall. I could see an AHL contract with the Penguins, where he'll spend most of next year with Wheeling. Quite a few players do that I believe, I remember Reid McNeill stayed with WBS for 4 or 5 years and never got a NHL contract from the Penguins. It's not very common that those kind of players pan out into NHLers, though. I need to know what the Penguins think of guys like Pedan before I say whether the Penguins will sign him or not. Do they think Pedan actually has some sort of NHL potential, or is he just a warm body that was thrown in for Pouliot?
