Take a look at the four biggest mistakes the Bruins made that prevented them from sweeping the series.
1. Derek Stepan steals the puck and scores: "I wasn't aware he was right behind me," defenseman Zdeno Chara said after having his pocket picked on the play. "I've got to make sure I take a look."
2. Dougie Hamilton fails to stop Chris Kreider: "Right now, for me, that last goal obviously bugging me and that's a play I have to have and just feel like I kind of let the team down," said Hamilton. "Just pretty upset right now."
3. Bruins called for too many men on the ice and Rangers score tying goal on ensuing power play: "I think it was my fault," winger Tyler Seguin said. "I saw Thorty [Shawn Thornton] coming. I hopped over, and I think he got hit. I haven't seen the replay. He stayed on for an extra second. I don't know exactly the ruling. Our centerman, whoever was out there, touched the puck, not me. I don't know if that's too many men, or if I touch the puck, it's too many men. Regardless, I think it was a close call. They made me pay for it."
4. Tuukka Rask falls, Carl Hagelin scores easy goal: "I just took a step to the side in what I think there was probably a skate mark or something," said Rask. "My skate dug in it, that's what it felt like, and then I lost my balance and the rest is history. It happens to me twice a year in practice, maybe. Focus, got to be more focused, I think, but just a tough mistake. It looks pretty bad on TV, I bet."
