It also was because 'both' goalies got two-year offers elsewhere in FA and Lou had to match. Marty wanted lockout protection and Moose wanted the extra year to relocate his family. Other teams were willing to give it to them.
If Lou didn't, the goalie FA market was BAD last year. Montoya, Chris Mason and Gustavsson were the top goalies period that moved in FA. Bobrovsky wasn't available to 'us' in trade and they would have had to pay a pretty penny to trade for other unproven guys like Lindback.
I don't really see anything else Lou 'could' have done this offseason. Especially given how well both played last year.
Marty was a no-brainer...even if the second year had the potential to blow up (which we won't know until the '13-'14 season is well underway). Everyone involved likely knew the Devils would be getting a diminished version of Marty, but one they could live with, especially to see him retire a Devil. Like I said, a risk, but one I think Lou had to take, especially considering the player, and I think he did so willingly.
I think if Lou felt someone in the system was close, he probably would've let Hedberg walk. But yeah, between there not being being great options out there and uncertainty about what the Devils had in house, I think Lou probably gritted his teeth a little with the Hedberg re-signing. He probably didn't love giving him that second year.
