Hoffman being at camp, IMO is a sign they want to carry him as their 14th forward going into the season which makes sense. He deserves a chance in the NHL and has paid his dues, worked hard, and really done everything the organization has asked.
There is no question they will need extra bodies this year, I would guess 14 forwards and 7 D man for sure. The wild card in all of this is Noesen, will he get that 5 game look that a lot of people believe he is ready for and they ship Hoffman back to Bingo and wait... guess we'll see who out performs who.
On the blueline, short of making a trade they are starting the year with Borowiecki, Weircioch, and Benoit which wouldn't be the worst thing in the world IMO. They are playing and playing well.
