On the postgame Mike Milbury and Jeremy Roenick go toe-to-toe about the Letang hit. Roenick presumably jumped in to troll Penguin fans:
Roenick says Letang was hit in the chest. He also goes on to blame Letang for the hit and said Letang needs to learn to take a hit.
Here is the hit gif'd.
Sure looks like the head was contacted to us.
