NHL free agency began on Tuesday, and the Chicago Blackhawks kicked off the week with a trade. The Blackhawks announced Tuesday morning that the team has re-acquired forward Sam Lafferty in a trade with the Buffalo Sabres.

Hawks general manager Kyle Davidson has now executed a whopping four Lafferty trades — three in which he has acquired the speedy forward.

Blackhawks make a familiar move to boost bottom-six depth and strengthen the penalty kill ahead of a strategic offseason.
