The 25-year-old Bollig was an NHL rookie last season, playing in 22 games, including four playoff games. He has eight goals, seven assists and 285 penalty minutes in 111 career games over parts of three AHL seasons in Rockford.
The 23-year-old Smith has six goals in 26 games over the past two seasons. A sixth-round pick in the 2008 draft, Smith had 15 goals and 16 assists in 38 games with Rockford this past season.
The Blackhawks also said Monday they have agreed to terms on a one-year deal with goaltender Carter Hutton and released goaltender Alexander Salak.
They said, 'You're going to love the city. It's smaller than Philadelphia, but you're going to love it. You're going to love the fans. Just watching the playoffs last year, the fans seemed louder there than they did anywhere. I'm really excited about that.
