The way I see the draft going, I don't think we will have a chance to draft Lindstrom, so the choice, unless we move up, would be between Iginla and Catton.
In this writer's opinion the top 4 picks will be: Celebrini, Lindstrom, Buium and then Dickinson. That Celebrini will be going 1 OA is now pre-ordained. I see Lindstrom, despite the injury concerns, going second. When the former NY Football Giants GM, George Young was asked what his draft philosophy was , he responded: "I like big men who can run". I firmly believe that a similar approach aptly applies to hockey and I can't see too many teams, if given the opportunity, passing on this very large player who possesses excellent skating and hockey skills.
As for Buium, people are still kicking themselves for not taking Quinn Hughes in the 2018 draft. You pass on the type of skating ability that Buium brings at your team's peril. Dickinson's play so far in the OHL playoffs shows that he offers a plug and play NHL defenceman for the next decade. He's big, mobile, physical, has a great shot and is a team leader. He has captain written all over him and if he leads London to a Memorial Cup win, I could see a team taking him at 2 OA.
Then, if I'm correct in my assessment of the draft, it will come down to a choice between Iginla and Catton. Both will be impact players in the NHL. One, Ignila is a better goal scorer and and plays a more physical game. Catton is a better play maker and probably has better offensive vision. To me, between the two, I go with the scorer, who is also one of the yougest draft eligible players in the draft. But it's so close, I could change my mind tomorrow.
Bottom line, unless Hughes makes a colossal overreach, we're getting an elite prospect at 5 OA who will be a principal driver of our seemingly endless re-build.
As I have said, this is a great draft to be sitting between 2 OA and 7 OA. Everyone drafting in those positions will (should) be getting a core player.
