Dickinson LD is a good player, he has good size & plays a good defensive game, has some edge to his game & can put up some pts, he would be a good addition to Ottawa's prospect pool, no question about that. However, having said that, it could be argued that Kleven LD is a similar player, maybe less offence, while most here will argue Dickinson will be better, it's possible, we'll see. Ottawa also has Donovan LD who has similar size, a very good skater & can also add some offence. I wish Dickinson was a right shot, he'd be perfect.
What Ottawa needs is a defenceman like that on the right side, they have their left side set for the next 5 yrs IMO & need to fix the deficiencies on the right side. There will be other drafts to add to that position in future drafts, remember we have a very young team. If they were to draft Dickinson I would be fine with that, but he doesn't address the immediate and/or future problem on the right side in their prospect pool. Guennette RD may have an outside chance, but so far in his viewings at the NHL level he's been mostly meh.
I view Dickinson & Yakemchuk as somewhat similar players, one is much better defensively while the other is much better offensively & what Ott needs IMO is a more offensive right shot D who plays with a mean streak & brings some sandpaper to the defence. Zub plays a good defensive style. I value right shot/left shot players in their proper positions more than most though & NHL executives value right shot D highly. The other point to consider is how good a team London is that Dickinson plays for while Yakemchuk plays for a rather poor Calgary Hitman team that was offensively challenged all yr & he still managed as a D to be their second leading scorer. I wonder what Yakemchuk would look like on London's team & speaking of the London Knights it's too bad Ott didn't consider hiring Dale Humter to coach this team.
