Frolik is coming off a Stanley Cup win with the Blackhawks, and scored three goals and seven assists in 23 post-season games this year. He is scheduled to become a restricted free agent after his current deal, which carries a cap hit of $2.33 million US, runs out after next season.
The 25-year-old native of Kladno, Czech Republic is a two-time 20-goal scorer, but only found the back of the net three times this past season for Chicago.
In 349 career regular season games, the 10th overall pick by the Florida Panthers in 2006 has 69 goals and 151 points.
Winnipeg surprised many observers by going with defender Josh Morrissey with the 13th pick in this year's draft, a jump of at least a dozen places from where some thought the Prince Albert Raider might go.
A left-handed shot, Morrissey had 15 goals and 32 assists to go along with 91 pentalty minutes.
