He was the Leafs' 2nd best forward last year, definitely a top-5 player on the team, and they made the playoffs.
And if he's not top-5 on the team right now, he's damn close.
He doesn't have to be a top 5 player on the team, which for the last month would be debatable, in order to be a contributor to a team's success.
Teams have more than 5 players and hopefully all of them are contributing.
Kadri last year was probably one of the top 5 reasons for the playoffs, quickly in no particular order, Kadri, Matthews, Andersen, Nylander, Marner, van Riemsdyk, Gardiner, Rielly were all major players in last year's playoffs position. To put it in order, I'd go with van Riemsdyk and Nylander out of the top 5, and perhaps Rielly. Really hard to suggest Matthews, Kadri, Andersen wouldn't be top 3 in some order.
Even if he was 10th. most important player going forward that wouldn't be an insult whatsoever ... say Dermott and Liljegren come up and blow everyone away and Kapapen joins Marner and gang amongst top producers, I'd still be happy to have Kadri plying his trade with the team.
Right now something seems a bit off with Kadri, but it started before the concussion concern.
Since November 30th. Kadri has one goal, one point. Fact not opinion others can discuss their opinion on why, but I think there is something there.
