Brady Tkachuk, LW -- The No. 4 pick in the 2018 NHL Draft signed an entry-level contract with Ottawa on Aug. 13 and will compete for a roster spot this season. The Senators are weak at left wing, giving the 18-year-old a chance to land in the top six and potentially on the first line with Duchene and Stone. If Ottawa trades Stone and/or Duchene, don't be surprised to see Tkachuk find chemistry with a rookie center in either Colin White or Logan Brown. Tkachuk likely will be overshadowed by his team's concerns in fantasy drafts, but had 31 points (eight goals, 23 assists) in 40 games as a freshman at Boston University last season and could be a dark horse for the Calder Trophy.
Thomas Chabot, D -- The 21-year-old could be fantasy-relevant over a full season with power-play duties to himself after Erik Karlsson was traded to the San Jose Sharks. Chabot played on the first unit with Karlsson down the stretch last season and had 25 points (nine goals, 16 assists), including eight on the power play, in 63 games. He played for Canada at the 2018 IIHF World Championship and will be the foundation of Ottawa's rebuild along with Tkachuk, making each of them a sneaky late-round pick in a one-year league and much more valuable in keeper/dynasty formats.
Other players with fantasy upside in late rounds or off waiver wire: Colin White, C\\; Craig Anderson, G; Logan Brown, C; Bobby Ryan, LW/RW
