In 2010 the Hawks won the Cup with Keith (6'1") and Campbell (5'10") playing top 4 minutes. Their biggest D man was the size of our current roster's 3rd tallest D man.
In 2011 the Bruins won the Cup with Ference (5'11") and Seidenberg (6'0") playing top 4 minutes.
In 2012, the Kings won the Cup with Doughty (6'1") and Voynov (6'0") playing top 4 minutes. Their biggest D man was the size of our current roster's 3rd tallest D man.
In 2013 The Hawks won the Cup with Keith (6'1") and Oduya (6'0") playing top 4 minutes. Their biggest D man was the size of our 3rd tallest D man and their bottom pairing was 6'0" and 6'1".
In 2014, the Kings won the Cup with Doughty (6'1") and Voynov (6'0") playing top 4 minutes. Their biggest D man was the size of our 3rd tallest D man.
In 2015 The Hawks won the Cup with Keith (6'1") and Oduya (6'0") playing top 4 minutes. Their biggest D man was the size of our 3rd tallest D man and the 3 guys they rotated in the bottom pair were 5'10", 5'11" and 6'1".
In 2016 the Pens won the Cup with Letang (6'0"), Lovejoy (6'1"), and Daley (5'11") in their top 4. Their biggest guy was 6'4" (our 2nd tallest player) and no one else was above 6'2"
In 2017 the Pens sized up a bit on their blue line, with a top 4 all above 6 foot.
In 2018 the Caps won with Orlov (5'11"), Niskanen (6'1") and Kempny (6'1") rounding out the top 4 after Carlson (6'3"). Their biggest guy was the size of our current roster's 3rd biggest guy.
Our group in 2019 was the biggest group to win it by a country mile. Dunn was our smallest D man at 6'0" and everyone else was 6'2" or taller (with 4 of our 7 regulars being 6'4" or taller).
Tampa continued the trend of big blueliners with a core above 6 feet tall (although not nearly as big as ours).
Here is the list of 6'4" D men who played 200+ minutes on a Cup run in the last dozen years: Hedman, Parayko, Bouwmeester, Edmundson, Bortuzzo, Dumoulin, Chara, and McQuaid. Our team and the 2011 Bruins team are the only group that had more than 1. We currently have 2 such guys with a 3rd who is 6'3". The large half of our blue line has better reaches than 11 of the last 12 Cup winners. You can't point at the small half and say "no one has had success with a small half like that" without acknowledging that no one else (besides our GM) has built a large half of the blue line as big as ours either. If your argument is about reach, you can't ignore that half the blue line has much better reach than the large majority of Cup winners
Our current blue line has an average height of 73.33 inches
The average height of Washington's blue line in 2018 was 73.16 inches
The average height of the Pens blue line in 2016 was 72.83 inches
The average height of the 2015 Hawks blue line was 73 inches. 73.33 inches in 2013 and 73.16 in 2010.
The average height of the 2014 Kings blue line was 73.83 inches. That number was 73.5 in 2012.
The overall reach/length of our blue line is right in line with the majority of Cup winners over the last dozen years. If you are talking about the construction of the whole group, then we don't have a height/reach issue. If your talking about the size/effectiveness of individual players, there are plenty of examples of individuals being very effective under 6'0". Again, Krug and Perunovich have deficiencies in their games that create a high likelihood that we'll need to add a piece from outside the organization. Reach is not it.
