Barring a trade, the group of NHL players that will show up to Sens training camp in September is pretty much set. In terms of contracts in-and-out, there really hasn't been much change to speak of. However, if you compare this roster to the one we saw at the end of 'The Streak', there's a marked difference.
As a reminder, here was the lineup entering Game 82 vs. Philadelphia:
MacArthur - Turris - Stone
Hoffman - Zibanejad - Ryan
Condra - Pageau - Lazar
Smith - Legwand - Chiasson
The entire top-six *should* be intact, with the emphasis around should because it honestly depends where Dave Cameron decides to play Mike Hoffman: on line two or on line three instead of the currently-absent Milan Michalek.
