Blacker is notorious for taking his sweet time when he switches leagues. He did so in the OHL and now doing in the AHL. However if you follow him enough you should be able to notice his offensive flare showing. He's putting it all together slowly but steadily. If anything when he's ready he'll shine quite well. He was an absolutely threat in the OHL when he had his head on and lead a full charge. I'd expect something similar when he does so soon.
Kenny Ryan will be a hockey player in some way or form, he has way too much drive and character not to be one. He's what you can that great team player everyone covets. His offensive isn't as strong as I'd hope but give him time and he should come out possibly as a really good third line grinder with offensive game. If you want a powerforward with offensive flair you should look for that in Carter Ashton. Slowly yet steadily hopefully he'll come around, very raw but IMO with the right patience his offense may help us get a top 6 forward with powerforward capabilities.
