If it's possible for a player to have a first professional season that's both impressive and disappointing, Ryan Culkin's may be the best example of that.
A native of Montreal, Culkin made his pro debut last season with the Adirondack Flames and slowly but surely became one of the team's best reliable defenders. His offensive production came in fits and starts, but he ended up being one of the team's better positional defenders. His scoring peak came with a seven point performance in the month of December, but you could argue that his plus-7 rating in January was perhaps his most impressive statistical feat.
