Should Bruins goal have been disallowed?

The Winter Classic was a thrilling overtime game in which the home team won.

But should they have?

Below are a couple of pictures that prove the Bruins not only had two extra guys on the ice when they were coming out of their own zone on the way to scoring the winning goal (first picture), but also that they had one extra guy still on the ice as they entered the Flyers zone (second picture).

Only four players plus the goalie are allowed on the ice at one time in overtime.

The refs missed this one and it cost the Flyers.
