Patriots' Marte Mapu sends powerful message after first career interception

Marte Mapu stood out during training camp this past summer, but the rookie linebacker hasn't gotten many opportunities on the field. 

Yet on Sunday, he took advantage of the time in the Patriots' loss to the Chiefs. And I'm sure it was a day he won't forget in his career. 

In the second quarter, Mapu recorded his first career interception, giving the offense the ball in the red zone.
