2,556 – Days since the last five-on-five Capitals goal scored with three forwards under the age of 23 on the ice prior to last night’s Evgeny Kuznetsov (22 years, 262 days old) tally, on which Tom Wilson (20-313) picked up an assist and Andre Burakovsky (19-361) caused some havoc in front of the Sens net.
The previous such score came almost seven years to the day before this one, when Alex Ovechkin (22-146) scored with Nicklas Backstrom (20-085) and Eric Fehr (22-160) also on the ice on February 6, 2008 against Philly.
(H/t Hockey-Reference for providing the tools that make a search like this relatively painless.)
