Two of the first four games took more than one overtime to settle. To make matters more difficult, each of those marathon games came the night before a travel day.
The Blackhawks won Game 2 3-2 in the third overtime to even the series at 1-1 the night before the series moved to Chicago. Each team flew to the Windy City less than 12 hours after Marcus Kruger scored the overtime winner the night before.
Saturday, in Game 4, Antoine Vermette was in the right place at the right time to give the Blackhawks a 5-4 win at United Center at 5:37 of the second overtime, evening the series at 2-2.
But neither team believes fatigue will be an issue in what is now a race for two more wins in the best-of-7 series, beginning Monday at Honda Center (9 p.m. ET; NBCSN, CBC, TVA Sports).
