Hall on Monday said he would like to see the Devils add to their talent as he enters the final season of his contract with the potential to become a free agent next offseason.
"We have the culture and character in our locker room, but at this point in time, in my opinion, we lack some talent in positions," said Hall, who won the Hart Trophy, voted NHL MVP, last season. "Whether it's the players on our team getting better and improving, or from the outside. Certainly, when you finish 29th, you're lacking some skill and lacking some talent. The great part is we have a culture in our locker room that's fun to be around and conducive to success and hard-working people. Now it's about filling those gaps where we might have lacked this season."
