Vince Dunn

Dunn took another step forward last season by notching 12 goals and 35 points -- eight on the power play -- over 78 games. Although Dunn's defensive-zone play could use some work, he often worked on the top power play as a quarterback for guys like Vladimir Tarasenko and Ryan O'Reilly, proving the 22-year-old is just a year or two away from being a top-pair talent. The Blues are likely retaining their blue line, except for Joel Edmundson, but both Carl Gunnarsson and Jay Bouwmeester are aging and susceptible to injuries, so Dunn could become the team's top left defenseman. While depending on injuries is ill advised, Dunn should be considered a late-round sleeper pick since his ceiling could be around 50 points if the Blues' power play shows competence this season.

The 2015 second-round (56th overall) draft pick entered training camp last September tired of the AHL lifestyle. And by tired, we mean hungry for more challenges. Dunn stole the last spot on the blue line from 2012 first-round pick Jordan Schmaltz and cemented himself in the top four by the end of the season. Dunn managed five goals and 19 assists in his rookie campaign while averaging 17:14 per game with power-play duties, where he posted nine points. The 21-year-old has superb puck possession as well -- he finished with a 54.7 Corsi For percent -- earning him a spot at World Juniors with Team Canada, which is a tribute to where his game can go. With a re-invented offense to complement his game, Dunn appears to have a strong chance to surpass 35 points in 2018-19, especially when teamed up with Colton Parayko.
