Kettani is in the midst of serving a seven-year commitment to the Navy reserves, while pursuing his NFL career.

But not everyone is pleased with Kettani’s decision to leave active duty to pursue his dream of playing in the NFL.

“I received some hate mail, saying, ‘Go back to the military, do your job, and do what you signed up for,’” Kettani said in an interview with the NFL Network. “They have every right to say that.”

Kettani served two years of active duty for the Navy after graduating in 2009, doing counter-terrorism work. He was signed by the New England Patriots in 2011, but was recalled to the the Navy and never played a down.
