Tried to find as much video on O'Brien as I could. Looks like he's a strong defender. Big, really lengthy. Has some offense to him but not a ton.
Few clips I saw he did make some mistakes while under pressure though.
Should add some size, snarl, maturity to the backend. If I had to guess Letang let Seca know that he thinks there backend lacks those things & that's why he was signed. Fischer/Bodin/O'Brien probably be a trio he'll use a ton on the PK and late in games while winning (if they ever start doing that again)
Andersen gonna have a hard time getting in the lineup. Would prefer they sent him down to the legionnaires. Omeri probably be sent back to Collingwood or let go/traded.
Once Young returns assuming what his injury is isn't season ending, Barr or Bridgewater will be sitting and I'm not a big fan of that.
Let's hope Jack can help stabilize the backend. It could use it. Also see if Fischer somehow avoided SSPD or if they r gonna announce it tomorrow.
