Just for more fun (read: frustrating), here's a comparison someone on LGP did between so-called defensive defenseman JJ and Gill and Scuderi from 2009...
"First, if anyone is out there saying "Jack Johnson's Corsi sucks, he's a horrible player, why can't the Penguins see this," you should question that person. Even in my big post above, first thing I did was throw out Corsi. Is Johnson's Corsi good? No, BUT.....everyone gets hung up on Corsi. Corsi isn't the problem. It's when you keep going down the line, looking at actual SOG, Scoring Chances Against, Goals Against, High Danger Chances/Goals.....ALL OF THOSE NUMBERS ARE BAD FOR JACK JOHNSON. ALL. OF. THEM!!!!!
To answer the question about Johnson compared to Scuderi and Gill in the 2008-2009 season (using 500 minutes TOI as minimum, and looking at even strength):
Corsi For%:
--JJ, 45.52%, last out of 7 defenseman on the team
--Scuds, 46.15, 5th out of 6 defenseman
--Gill, 48.34, 3rd out of 5 defenseman
Shot For%:
--JJ, 44.45, 7th out of 7
--Scuderi, 47.79%, 5th out of 6
--Gill, 49.13, 3rd out of 6
Goals For%:
--JJ, 44.57, 7th out of 7 (only one under 50%)
--Scuderi, 59.05, 1st out of 6
--Gill, 56.58, 2nd out of 6
(This should be your first staggering indicator. Two true defensive defenseman LEADING in GF%, on for more Goals For than against. Letang is last in 2009, only player under 50%. Scuderi, in 81 games, was only on the ice for 43 even strength goals. Jack Johnson is already at 51 with 20 some games left)
Scoring Chances For%:
--JJ, 47.32, 7th out of 7
--Scuderi, 47.87, 5th out of 6
--Gill,, 51.63, 3rd out of 6
High Danger Goals Against%:
--JJ, 31 total, 43.64%, both numbers 7th out of 7 (again, only d-man below 50% on the team)
--Scuderi, 26 total, 58.73%, 4th in total against, 2nd in HDGF%
--Gill, 20 total, 2nd in total against, 3rd in HDGF%
Offensive Zone Start %
--JJ, 49.19%, 1st out of 7
--Scuderi, 44.52, 6th out of 6
--Gill, 45.76, 5th out of 6
I mean, if that doesn't paint the picture, anyone still defending Johnson might just be part of a cult. Gill and Scuderi, two defensive defenseman, got more defensive zone starts than anyone else percentage wise, as you would expect...yet Johnson gets the LEAST percentage wise. Gill and Scuderi, two rather offensive inept defenseman, have very, very good GF to GA ratio/percentage....Johnson....doesn't. Not only does Johnson not have good numbers, but he ranks last or next to last out of all our defenseman. Scuderi and Gill were middle of the pack, not near the bottom.
Johnson is not good. Damn, I need to fire up my blog again and put all of this....Gudas comparison, Scuderi/Gill comparison, into one nice place for reference."
