The criticism of Kadri is really bordering on hilarity at this point. He's not a Selke winner but my god. Has anyone taken a look at Phil Kessel? How about we take a trip in our time machine to the Phil Kessel during his first few years with the Leafs. The guy couldn't be bothered to skate back into the defensive zone. Now keep in mind that Kadri is 3 years younger than Kessel.
The 2009 draft was a pretty decent draft so far. Kadri was picked 7th overall and is the 7th highest scoring player out of that draft. On a per-game basis he's top 5 in both goals, assists and points. Seeing as the only guys he's behind on a per-game pace were drafted ahead of him, the criticism seems a little over the top.
He hasn't taken that next step this year, but it's also his 2nd full NHL season and that's pretty common for a guy to struggle. Now take into account that he's played with Clarkson for good stretches of the year and that the team as a whole has played like refried garbage and I'm not sure how closely we need to look at Kadri as the most disappointing player on the team. He still has had a better offensive season (cumulative totals not PPG) than Bozak has ever put up in a season despite 2nd/3rd line ice-time and 2nd unit PP time all year.
There are definite flaws that need to be addressed. I think his skating took a half-step backward this year. Something has happened that he isn't trying to be nearly as creative with the puck (coaching staff?), his defensive play has been disappointing for large stretches, and while I'm not surprised about his slowed offense, the team could have used a few goals from him in the last few weeks.
