A couple of things. Walski isn't so young any more, though most of us expect Eidsness will be the primary goalie. You never know, though. Hard to argue with Walski's stat line...
As for Eidsness, I have high hopes like many others. However, I hope we are realistic. There have been many comments on this board about "if" Eidsness can come in and play like Bachman or Kangas. I don't know how often that happens as a freshman. It would be great but hopefully we're not expecting too much of the young man in his first year.
As for Harrington, I'm guessing he's been made pretty clear that his chances are not great of playing all that much, but at the same time like any position on the team, you can practice your way into the lineup.
