Weird Braun/Holl argument going on in here. A bunch of people want Braun and see him as a top 4 upgrade on Holl, a bunch of others think he's roughly equal to Holl and don't want to waste assets on an player who isn't a "clear upgrade".
Why does Braun have to be a clear upgrade on Holl to be worth trading for him, if you're arguing Holl is a 4 and Braun is a roughly equivalent 4 wouldn't it be a good thing to have one of them on your 3rd pair? Since when is having a capable top 4 defenseman playing on your third pair in the playoffs a bad thing? Obviously it improves your defense as a whole, not to mention injuries.
I like Braun because if/when Holl or Muzzin go down we are really lacking in the size, physicality and PK ability on the back end. Who's our #1 RD PK option if Holl goes down? Lily (Brodie maybe)? A lot to ask of a rookie D on a cup contender, and not a role Brodie has excelled at in his career. Braun's cap hit is cheap and hopefully cost wouldn't be too high as well.
Would it be great to pick up a top 2 or top 3 level d man, of course. But those are hard to come by, expensive to acquire and typically come with a big cap hit that we may or may not be able to fit. Plus the guys out there who fit that description (Lindholm, Chychrun, Klingberg) are more puck moving and offensive guys where our bigger need is PK and shutdown type of guys.
