Ristolainen has increased his point total (45 last year) and ice time (26:28) for three straight seasons, establishing himself as one of the league’s best young defensemen. He simply does it all for the Sabres: playing against the opposition’s top forwards, quarterbacking the powerplay, and killing penalties. The sky’s the limit for Ristolainen, who’s arrow should continue pointing up on a team that looks vastly improved on paper, and he remains Buffalo’s undisputed No. 1 defenseman. It would not be a surprise to see Ristolainen crack double-digit goals while registering his third consecutive 40-point season. Ristolainen is the present and future of the Sabres’ blue line, and it’s not unreasonable to expect him to be a top-10 scorer among defensemen. He also improved his rating to minus-9 last year (from minus-21 the year before and minus-32 the year before that); it'll be huge for his fantasy value if Ristolainen can get himself to the positive side of the ledger in 2017-18.

Ristolainen is the Sabres’ undisputed No. 1 defenseman, and perhaps the best young blueliner in the league. The 21-year-old appeared in all 82 games last season, averaging 25 minutes per contest and often quarterbacking both power-play units. He's one of the shiniest stars in a golden era for Finnish hockey, having improved his point total to 41, with his 32 assists tying young star Jack Eichel for second place on the team. As the Sabres improve, so should Ristolainen’s plus-minus, which sits at a composite minus-68 after three seasons. It wouldn’t be surprising to see Ristolainen top the 50-point mark next year as the 6-foot-4 dynamo continues growing into one of the game's premier two-way defenders.

Despite his ugly minus-32 rating and rather meager total of 20 points in 78 games last season, the 20-year-old Finn is Buffalo's blue-chip defenseman and a player expected to take a big leap forward in 2015-16. With a thin blue line, the Sabres can't protect Ristolainen, but given his size, skill, and how well he's handled the pressure so far, there shouldn't be much to worry about as he continues to develop. He's locked in as one of the team's top-four defensemen and could be an intriguing late-round fantasy target.

The 19-year-old Ristolainen is Buffalo’s top-rated young player on defense, and will likely remain with Buffalo for the entire season in 2014-2015. Though his production was muted in his 34 games with the Sabres last season, Ristolainen was a key player for the team’s AHL affiliate in Rochester, scoring 20 points in 34 games. Ristolainen is at the forefront of the Sabres’ rebuild and is poised to make a greater impact this season. There will be growing pains as Ristolainen develops into a franchise defenseman, but if everything goes right, he should emerge as the Sabres’ best defenseman by season’s end.

Keeper leaguers should familiarize themselves with Ristolainen, the 8th overall pick in June�s NHL Draft. The 6�3� defenseman is expected to compete for a spot with the Sabres this fall after posting 15 points in 52 games for Turku in the Finnish league last season. Ristolainen is one of the top prospects among defensemen in all of hockey, with strong mobility and a cannon from the point. Since Ristolainen is just 18 years old, you should temper your expectations in one-year leagues, but be ready to pounce if he makes the big club and starts strong.
