There are a lot of teams that seem to be interested in D early in this draft. I wouldn't be too surprised if both Dallas and Colorado take a defenceman, and both Arizona and Buffalo also need D. I think if JB is planning on taking the best available center, he should leak some info that we are thinking of taking a Defenceman.
If say Heiskanen and Makar go at the 3 and 4 spots, you've got to think that Arizona or Buffalo would start to panic a bit, and would be willing to trade up - ie swap with us to ensure they get the best available D remaining. They then take Liljegren, Vegas takes a center or maybe even Tippett, and that still leaves us picking a really good center (one of Vilardi, Mittelstadt or Glass). I read on the the Buffalo HF board, that they expect to take a D and would be willing to trade up using both of their 2nd round picks. If JB plays the 2 teams against each other he might even get Arizona's late 1st, or maybe a good young forwards like Duclair or Fischer... just for moving back a couple of spaces and picking the guy we want anyways.
There should still be a lot of good players to pick from in the late 1st/early 2nd, so instead of 1 of these, we could get 2 or even 3....
Jokiharju, Vaakanainen, Joseph, Braanstrom, Thomas, Dolan-Anderson, Strome, Frost, Bowers, Boqvist, Mattheos, Mismash, etc.
