I like Russell Maxwell from the Lethbridge Hurricanes. He is listed as 5'8" but is probably even smaller. Last year he had 31 points, but is sitting top 25 in the WHL with 20 points in 19 games. Has the heart of a lion and not afraid of anything, drops the gloves quite a bit for a guy his size.
Enstrom is the best small player in the league I guess after St. Louis and it's funny how his D partner is oversized Byfuglien (yet Enstrom is better at actual defense of the two). Also a Spurgeon fan.
Theo Fleury has to be the best small hockey player of the modern era.
I love Daniel Catenacci towards the future. Drafted him in one of my keeper leagues two years ago. Was a former 1st round selection in Junior and the top skater in the CHL 2011 Top Prospects game. Is quite feisty and tough for his size. Think a Theo Fleury, but slightly a bit bigger.
