Roos inked an entry-level, two-year contract with a $925k cap hit, and comes in as 6'4» and 190 pounds. In 50 SHL games with the Skellefteå AIK, he has six points (1G, 5A) but has previously earned 40 points (7G, 33A) in Sweden's second highest league, HockeyAllsvenskan, for BIK Karlskoga.
The 23-year-old Sweden native is the first to sign with the Hawks in the offseason and is described as «a big body who possesses strong skating abilities for his size» by Davidson. Roos's contract means there are now 14 defensemen signed on the Blackhawks for next season. It's unclear whether Roos will be starting down in Rockford or immediately thrown in the show.
