IMO NHL front offices shouldn't do anything blindly let alone blindly pick a player because of the position they play. Yes, we need a center for the future but would you, hypothetically, rather use this very valuable pick on a good middle 6 center or a potentially great top line winger? Player comps tend to be silly, but, using Pronman's comps, would you rather have Jason Robertson (Martone), Elias Lindholm (Desnoyers), or Mika Zibanejad (Frondell)? Sounds like you would take either of the centers just because of the position they play...which I would disagree with in this made up scenario. No one knows what these prospects will become or how teams ultimately have them ranked but if the Bruins do have a winger (or defenseman for that matter) clearly ranked ahead of a center, then I hope they take the player they think will make the most impact in the NHL.
No one knows what the NHL roster will look like in 2, 3, 5+ years. If the Bruins sign Eichel next year, suddenly our need for a top center isn't so pressing, is it? Even if they don't sign Eichel, if Martone takes off and his stock increases, then you're better positioned to trade him for a center down the line if needed. You draft the best player you can and figure the rest out later.
PS: Spare me the "hoW CaN yOu tRuSt SwEenEy's rAnKinGs? ThEy aRe gOnNa pIcK sOmE bUm" responses. The draft is a crapshoot and the Bruins have done just fine (if not better than fine) over the last several years considering where they were picking. This narrative is played out and adds nothing to the discussion. (This isn't directed at wintersej but rather all the other folks repeatedly making these comments in pretty much every Bruin prospect thread that was created in the last 10 years).
