I saw JJ dominate on the PP in college, I saw him when I was Europe this spring and he dominated at the WC's.
I have no idea why the Kings refuse to let him play on the #1 PP.
This may sound crazy but I have noticed when JJ and Doughty are on the ice JJ passes to Doughty but Doughty doesn't even look his way. Also, when Jack scores Doughty doesn't congratulate him like the rest of the guys on the ice. Another thing I noticed in an interview earlier this year when talking about the Kings young talent he mentioned everyone but Jack. Maybe there is something there that the Kings know but don't mind me, I've once thought my phone was tapped and I swear that my neighbor is siphoning my gas.
