This is a cluster ****.

?

Outside of Ennis I dont see better depth.

Dellandrea is a significant improvement over Janmark, and Braun is the defensive version of Gretzky compared to the pylon that is Roman Polak.

Ennis, Dellandrea, & Braun are all significant upgrades to the Stars depth vs. what they currently have in those spots.

Ty is unproven and looked totally lost when he did skate in preseason. Cogliano has scored 6 goals in 100 games, Janmark has scored 12 goals in two seasons so, that doesnt make any sense. Braun is a defensive dman no different than Polak or Sekera.
Ennis was the only depth add

Braun is definitely a better player than Polak/Sekera. Good #4 D.

Barely. You chose him over Ceci or Psysk? C'mon on man.

Braun is better than both of them....

Where did Cogliano come from? Take a look at the lineup that OP posted. Cogliano is still in the lineup, Janmark is not...meaning that Dellandrea replaces Janmark in this scenario. If we're being completely honest, Dellandrea would be an upgrade over Janmark, Cogliano, and Comeau. He looked fine this preseason and has been arguably the best two-way player in the OHL this year. He's easily a better bottom-6 option than the other players. Want to leave Dellandrea in the AHL for a year first? Fine. Robertson, Kiviranta, and Caamano would all be improvements over Janmark.

Are you seriously going to argue that Polak/Sekera are better than Braun? Go to this link (https://public.tableau.com/profile/bill.comeau#!/vizhome/SKATR2019-2020/SKATR), plug in the players and compare them. Polak & Sekera are 7th Defensemen AT BEST. Braun is still a top-4 defenseman, and would be a solid short-term option for Dallas.

Ty was in Texas this season and he looked awful in preseason,lol. Had he looked good he would be up instead of Dickenson. They have high hopes for Ty.
Letting Cogliano go before Janmark makes more sense.
Kivi sucks, the other two would be good as 4th liners.
Braun,Polak nor Sekera are top 4 dman.

Ty has been in the OHL all season with the Flint Firebirds
Cogliano has a year left on his contract. Janmark doesn't
Kiviranta is a fine bottom-6 two-way forward. He's essentially Janmark but cheaper
Braun is a fringe top-4 defenseman. The other two aren't even NHL-caliber defensemen anymore.

Ah, confused last year with this one. Doing well in the OHL isnt anything to get excited about,lol. Robertson put a goal record or something and look at him. Ty still needs time.
Kivi is fast and that's it. Hes Remi Elie and Gemel Smith rewind. Caamano and Robertson are better.
Okay, then both go. Cogliano is the worse forward on this team right now.
Yeah, Braun gets alot of PK time but, he rolls 3rd pair. He hasnt been a top 4 dman in 2 years. Basically letting go of Polak to pick up another Polak.

Braun has been given top four minutes at times this season and been very reliable/good in them. MUCH better than Polak lol.

No he hasnt. Last time he was a top4 dman was in 17/18. He plays on the PK, that's where his extra minutes come from. Take those away and he wouldnt get more than 12/13ish. 3rd pair guy.

Even Strength TOI/GP:
Roman Polak - 13:52
Justin Braun - 15:18

And in during that time, Braun leads Polak in the following stats:
Points (not that relevant for this discussion)
Corsi For
Expected Goal Share
Expected Goals Against
Relative Corsi For Percentage
Shots Against
On Ice Expected Goals For Percentage

Virtually every stat imaginable shows how abysmal Polak has been this season (and last). You can argue all you want that Braun is a "3rd pair defenseman", but if you're trying to tell me that Polak is even an NHL caliber defenseman then I don't know what to tell you. There's no world where Polak is equal to Braun at this stage in their careers.

15 mins still isnt top 4, lol.
Sekera is at 15 mins and he rolls 3rd pair.
On Philly he has the 6th highest minutes of 5v5 meaning there are 5 other dmen that play more than him i.e. 3rd pair.
Top4 is 17ish minutes 5v5

That's why I said...and I quote..."you can argue all you want that Braun is a 3rd pair defenseman,"

Even as a 3rd pair pair defenseman, he's miles ahead of where Polak & Sekera both are at this stage in their careers.

Comparing Polaks 41 games to Brauns 62 is dumb. Sekera played 57 so, let's stick with those two for this season then we'll compare Polak and Braun from last season.

Sekera:
3.2 point shares, total goals against 38, 3.8 defensive point shares, 1.1 goals against while on ice, 6 goals against short handed
Braun:
2.9 point shares, total goals against 58, 2.0 defensive point shares, 2.9 goals against while on ice, 6.5 goals against short handed

Braun has better offensive numbers than Sekera but, not by much. Sekera is a better depth dman than Braun. Now, let's compare Braun to Polak from 18/19.

Polak played 77 games,Braun 78.

Polak: 1.9 goals against while on ice, 6.8 Goals against whole short handed, total goals against 62, defensive point shares 4.6, 3.8 point shares

Braun: 2.7 goals against while on ice, 9.1 goals against short handed, total goals against 89, defensive point shares 1.8, 1.6 point shares

Polak is also a better depth dman than Braun.

Kudos on down grading, lol.
