So it's indeed true. The Devils have added Defenseman Vitaly Vishnevski to compete with a bunch for spots on their 2007-08 Roster.
Right now, you have to assume that the Top 3 is White, Martin and Matvichuk.
The last 3 will be filled out by either Rachunek, Greene, Oduya, Vishnevski, or Corrente. There's a case to be made for any of them.
