I think you are overreacting on the D situation. Not many teams have elite shutdown D-men playing on the first pairing. Florida is glad to have Barkov though who can make it real tough for top lines and help the D tremendeously.
Offensively Yandle is getting the points and Ekblad is on his 4th 10+ goal season, most likely to get his 2nd 15 goal season. In defense of Ekblad you also have to mention that he is playing his second season vs top competition and it is his first season doing so with being fully healthy. He has improved his skating and is taking strides to improve his overall game. He's mentioned that he needs to work on his skating and passing ability. He still has the potential and is only 22.
Also Matheson has taken great strides during his sophomore season, his skating is a joy to watch and he has good offensive instincts with a great poke check defensively. He'll also keep improving at 23, soon to be 24.
McCoshen should be able to take a full role next season so they will be locked down on the LHD in Yandle-Matheson-McCoshen. Perhaps it's still in question, but I'm still very high on him, he's had good moments and some not so good moments on his rookie season this year. He has a good history and a defensive mind, a prospect high on many lists in the past and has shown NHL talent.
To me questions arise after that. Pysyk has not played as well as expected this season and his future is in question. Also Petrovic is in a similar place. Weegar is a better puck mover and skater than etiher of them, I think they should just pursue a defensive specialist who can move the puck more as the 6th then. This leaves in question what the RHD situation will be with the team, I would perhaps keep Weegar as he has improved and at least has some potential in him. Pysyk & Petrovic play a similar role but might become expendable if Florida can get a tougher defensive specialist who can PK and get rid of the puck.
As a whole the team defense has also improved a lot, it's one of the youngest defensive cores in the league with everyone but Yandle being 25 or below. It's not as bad as you make it sound.
Also Gildon is a nice project, but he's years away from being a roster player.
True contenders have those guys, Hedman in Tampa, Doughty in LA, Chara in Boston, Keith in Chicago, Letang in Pittsburgh, pre last season(they though have Crosby/Malkin/Kessell to make up for it), Subban/Josi Nashville.
Franchise D-men have a massive impact in the game and on the finals.
If Florida wants to reach that level you need to be drafting D-prospects and you'll have a great shot this year.
For being a Wild Card team you don't need that, but why would that be the goal?
Look, Florida doesn’t have a great D but if there’s one bright spot in there its freaking Ekblad. He’s carrying the Panthers D on his back. Watch more hockey before spitting out dumb comment
I've watched enough Florida games in the last few years, and Ekblad is the opposite to what you are saying with where he was drafted.
He has failed to step up as the #1D in this league, with not being able to work on his weaknesses so far in his career.
If Ekblad was what you think he is Florida wouldn't be where they are today.
