Dustin Byfuglien is not an ELITE number one D. We are discussing Olli's potential of becoming an ELITE number one D. Elite Number ones play in all circumstances: head the PP, PK, 5on5, and they are excellent in ALL those situations. They log heavy and numerous minutes. No matter the circumstance, they control the game when on the ice. Olli did that for London and the Finnish national team, while leading both to championships, winning the award of top D, and at 17/18 years old, against (in many cases) players 2 years older.
