The Winnipeg Jets dipped their toes in the NHL’s free-agency waters this afternoon. After an hour of a frenzy that saw teams spend more than $335 million in the first 60 minutes, the Jets agreed to terms with centre Shawn Matthias on a two-year deal about 90 minutes after market opening. TSN reported the deal as $4.3 million over the two years. Matthias, 28, is a former second-round pick of the Detroit Red Wings in 2006.
