Watch hockey more. That's my best advice. First of all Karlsson hasnt even been in the league for 10 years. Despite his terrible season coming off a brutal injury and a long playoff run still had the best ppg of all d men in the NHL. All this on a terrible team dealing with as much adversity as a player/person can have. This is after a season being considered a top 3 player in hockey. If you actually watched him this season you would have noticed he was back to his regular self the last 15 to 20 games. His skating was fine, injuries take time to get over believe it or not. Karlsson is also 27 years old, as a d man that has elite hockey sense and skill he has 7 to 8 more good to great seasons. Your evaluation is terrible.
Hoffmans shot is elite his speed is elite. Put him with Mcdavid and He scores 40. He is certainly worth more than Sekera.
Given top 6 minutes Pageau has outproduced both Zibanejad and Brassard. Both in 35 plus game sample sizes while being an elite two way player. Right now he's probably the 4th maybe 3rd best all around forward on the Oilers.
I watch a lot of hockey. You should pay attention to what trades look like in reality instead of in your fantasy world. The Sens aren't getting a player of equal caliber back for Karlsson. It will be a package, and one that fans won't like. That's the way it goes when trading a star player for futures. Your homerism is coming through in a number of ways though.
1) Karlsson was considered a top 3 player in hockey by very few. And it was only for a short time during the playoffs that this term was thrown around. He isn't even universally regarded as the best defenseman in the game, and saying he is a top 3 player in hockey puts him behind only McDavid and Crosby, as those are still the clear 1 and 2 (in whatever order, that discussion is for another day).
2) Hoffman has good speed and a great shot. You still can't call him an elite scorer when he doesn't score at elite levels. Ovechkin is an elite scorer. Laine is an elite goal scorer. Hoffman was around 100th in the league in goal scoring this year. He's a good offensive forward. Not elite.
3) Hoffman playing with McDavid might score 40. He also might not score 30, we don't know if the two players would even have chemistry. We've seen enough scenarios in recent years where "x player will score tons with Crosby" and it didn't always happen. That proves there are no guarantees.
4) I don't think I said that Hoffman is worth the same as Sekera. If I did, I retract it because I agree, Sekera's value is at an all time low because he wasn't good after returning from his injury.
5) 35 game sample size is pretty small to count. Pageau is good, I agree, but he's a 3rd liner, with possible 2nd line upside. He's good, but a complimentary piece. There is no way he is the 3rd best forward on the Oilers. Maybe the 4th, but that doesn't make him a top six forward - we only had 3 top six forwards in our lineup this year (McDavid, Nuge, Draisaitl). He only has to be better than an awful Lucic, an emerging but not ready Pulujarvi, and an inconsistent Strome to be the Oilers 4th best forward this season.
