Nathan Walker

At 29 years old, Walker has yet to really establish himself in the NHL. He saw a career-high 56 games last season on a struggling Blues team, but he posted just 10 points to go with 82 hits, 35 blocked shots and 25 PIM in a bottom-six role. The Welsh-born Australian forward's peak is likely around the the 15-20 point range in a full season, but his on-ice brand of physicality can be easily replaced by most fourth-liners. Walker will also be at risk of potentially losing his place in the lineup to a prospect like Zachary Bolduc. Fantasy managers don't need to consider Walker for their rosters.

The NHL's first Australian player moved around a lot in 2017-18, having hit the waiver wire twice while contributing one goal in nine games between stints with Washington and Edmonton. The 24-year-old winger had a timely assist in his only playoff game and has endeared himself to the coaching staff with a pesky style of play and tenacious forechecking abilities. Walker will compete for a full-time roster spot with the Capitals this season, but he'll need to continue developing his skills to garner consistent ice time on the way to fantasy relevance.

Drafted in the third round of the 2014 NHL Entry Draft, the 23-year-old winger has plied his trade in the AHL ranks over the last few seasons. While he put up a modest 12 goals and 23 points in 58 games with the Hershey Bears in 2016-17, the hard-nosed Aussie has a legitimate chance to make the Opening Night roster for the Capitals in 2017-18, as he has the makings of a pesky forward that could have some modest fantasy value if he can garner consistent ice time, but remains a reach in all but the deepest leagues for the time being.

Walker made history this summer as the first Australian to ever be drafted by an NHL team when the Capitals selected him in the third round of the 2014 NHL Draft. The 20-year-old has a nice blend of speed and tenacity, but he is still quite raw and will likely spend the bulk of 2014-2015 in the AHL.
