Some good comments so far, I'll add a few, more like predictions though
Stepan - resigns for cheaper, or TDL
Tierney - is possibly traded, depending on Stepan
White - will move to 3C after one of Stepan or Tierney is traded
Norris - is on the team instead of LBrown, because of his speed, but he needs to produce at least at a 0.5 clip, or he'll move down the lineup
Zaitsev - still think he's around until the 2022 TDL, and maybe longer depending on if Gudbranson signs, and for how long
Gudbranson - Wait and see, if he's good with Chabot he stays, if he isn't then he's the more likely to go before Zaitsev
Reilly - has a partner in Zaitsev, which is a leg up on Wolanin
Wolanin - too solid to keep off the roster, might get blocked by Coburn
Coburn - can play his way into a spot, but will get pulled quicker than a pro's knickers on payday
JBrown - the Sens new Wideman, plays while he's in Ottawa
Murray - I'm hoping he steals a few games, but the defence is going to make Murray look pretty bad on some goals, be prepared for the negativity fallout
Edit: Let me clarify the Zaitsev comment, if Gudbranson isn't signed, Zaitsev might be around longer than the 2022 TDL. The second part of the Gudbranson comment, "and for how long", had nothing to do with Zaitsev. It was just an add to if Gudbranson resigned. I didn't word the entire comment very well, sorry.
Zaitsev - still think he's around until the 2022 TDL, and maybe longer. His time with the team also depends on if Gudbranson resigns, and for how long
