The list towards the bottom is the thing of interest. It breaks down the waiver-eligibility status of all Senators prospects. It should save time and clarify any questions about these sorts of issues if and when they arise during the season.
Note, too, the list of players who we can't call up, other than on an emergency recall basis, without risking losing them on waivers (St. Pierre, Brodeur, Carkner, and Hennessy) as well as the two players we have on AHL-only deals (Hamel and Yablonski).
EDIT: Oh wow. CapGeek is now test-running a "waiver calculator," which allows you to determine a player's waiver-eligibility status. It's not perfect yet, but, wow, a very handy tool!
