Keller flaunted his top-rate offensive skill set in a boon to the Coyotes last season, unloading 65 points (23 goals, 45 assists) in 82 games at the tender age of 19. Although he'd narrowly miss out on the Calder Trophy for top rookie, the 2016 seventh overall pick can take solace in the fact that he claimed Rookie of the Month honors twice (October, March) and cleared a point-per-game average over the final 20 contests. Keller also fired 212 shots on net and dropped an impressive 20 points on the power play. While his puck skills are undeniable, Keller didn't supply much fantasy value defensively with only seven hits and 28 blocked shots over the full season. However, Coyotes GM John Chayka made some shrewd offseason moves in an effort to improve upon the team's minus-45 goal differential, and Keller should reap the rewards if all goes according to plan.

Keller has accomplished a lot since being selected seventh overall in the 2016 draft. He ascended from the USHL all the way to the NHL in less than a calendar year with dominant stops at Boston University, the World Junior Championship and the World Championship. He projects to slide into an offensively tilted role with Arizona in his first full season in the league, and Keller owns the skill set and creativity to be a consistent scorer out of the gate. However, at just 5-foot-10 and 168 pounds, there will likely be plenty of offensive peaks and valleys throughout the season. Additionally, the rigors of an 82-game schedule could take its toll in the second half. Still, Keller's an elite talent with promising long-term upside.
