It's a lot of work to stay abreast of what's going on in the pipeline; most people don't care unless the NHL team is struggling/rebuilding (people are clamoring for Detroit prospect coverage).
Prospects I think are NHL ready today:
Sandin - he's very Dermotty, but far less risky; he's just smart, smart, smart about his positioning, angles, and reading of the game. Modern defensive defenseman. Just needs work on adding speed and it wouldn't hurt to get stronger.
Marchment - not a prospect in terms of age, but he has blossomed under the dev team and Marlies coaching staff. He adds an element that the Leafs do not have (he's a poop disturber in a power forward build) and would be slotting in at a low-leverage position.
Moore - not a prospect in terms of age, but other than his AHL scoring levels, I still maintain he's a left shot Connor Brown with far better wheels. He's an auto zone exit, entry, and a puck hound in the slot.
Prospects who I think are a year away:
Liljegren - still needs work to improve the range on some of his very good tools and playing dependably on a consistent basis. Best stretch passer in the system outside of Gardiner, and possibly already better (hard to tell with the different level of recipients).
Grundstrom - sounds like he's been working on his passing, which would make him a less simplistic attacker.
Engvall - He played shutdown minutes with Gauthier for the Marlies on their stretch drive last season, and offers that deployment some semblance of offense. He's deceptively fast for 6'4" and the additional reach just makes him all the faster on pucks.
Prospects I am very intrigued by:
Ian Scott - as you can see in the previous posts, Ian Scott found something during his time with the Marlies and it has translated to a more patient and positionally sound goaltender, basically stonewalling the WHL.
Sean Durzi - I think he's going to be a very fun add to the Marlies after the OHL playoffs are done, if the Marlies make it that far that is.
Mac Hollowell - He's too fast (of feet and mind) for the OHL; with the loss of Sandin and Timmins in the Soo, he now gets top offensive opportunities to round out his repertoire.
Pontus Holmberg - Wheeler pays some special attention to Holmberg; he appears to be of a similar mold as Johnsson, Brown, Moore, etc. Smart speed/space management.
Prospects I think we should have traded already:
