Goalies are voodoo, I would pencil Campbell in for 40~ games and run an on-going trio of smaller/older/overseas goalies at cheap contracts coming up and down from the Marlies. This way, you give Campbell his reps and you also get to weed out the non-performers and bury them. You also get some insurance as well in case of injury.
Guys to aim for: Dell, Anderson, Miller, Kaskisuo.
The thought of letting go of Andersen isn't popular and I'm not sure the kind of value a year rental at $5M will be perceived league-wide. There's also the 10-team NTC. It will all depend on where the team is at come trade deadline, getting rid of Andersen in the offseason and not replacing him with a similarly equivalent talent doesn't send a good message to the team.
