Seems that would qualify him for the perfect definition of "sleeper" pick.
He played last year with the big club for 2 games as an injury fill in and he scored a goal in both games.
Dubas strikes me as the kind of guy to reward success at the AHL level and Justin Holl was a key player in Marlies Calder Cup win. Now that Dubas is in charge of the NHL club, it will be interesting to see how many Marlies can graduate in the fall. Along with Johnsson, Grundstrom and Dermott, it’s hard not to see defensemen Justin Holl and Calle Rosen getting a longer look, too.

Five Marlies who have helped their NHL chances in Calder Cup Final run
When it comes to electric NHL debuts by Maple Leafs, Holl may have the best one in recent memory. Getting his first-ever NHL recall in early February, Holl courted headlines by scoring two goals over his two-game call-up, the only NHL action he’s seen since being drafted eight years ago. It’s been a long road to this juncture for the 26-year-old, including a 66-game East Coast Hockey League (ECHL) tenure,
but these AHL playoffs are putting on full display what would make Holl a welcome addition to Toronto’s blueline next season.
A big (6-foot-3, 205 pounds) right-shot defenceman,
Holl has been as reliable and consistent a defender as any in the AHL, pairing nicely with Martin Marincin, as he, too, blossomed into a stronger player.
Holl has just one goal and one assist in 13 playoff games, but as
Leafs head coach Mike Babcock said repeatedly when Holl was on his scoring spree, those offensive numbers aren’t what interest him when it comes to defencemen. It’s sound decision-making in his own end and crisp first passes on breakouts, among other attributes, that set Holl apart defensively and that have made him a top-pairing blueliner for the Marlies.
How all that will translate to the NHL full time only time will tell.
But Holl has been a reliable, consistent presence in the postseason while demonstrating that when the stakes are highest, he’s as trustworthy as they come – with or without the puck.
