The first time former Dallas Cowboys tight end and future Hall of Fame honoree Jason Witten retired from football, he went into a lucrative, high-visibility job as part of the Monday Night Football broadcast team. That rather infamously did not go so well. He came out of retirement, spent a year back with the Cowboys, signed for a very desultory season with the Las Vegas Raiders, and then retired again. This time he is opting to go into the coaching ranks. But rather than trying to vault right to the top of things, like he did with his broadcasting venture, he is starting on a much lower rung by taking the head coaching job at his children’s school, Liberty Christian High School in Argyle, a suburb of Dallas.
