Cowboys' Martin 'closer to the end' of his career
Briefly

I think I'd be lying if I said it has not entered my mind, right? I think it that's been a big thing for me this year just try to tell myself, 'Hey, go out, do your thing and let anything else take care of itself after the season. I don't know when I'll be done but it's definitely getting closer to the end. I think it's just a good reminder for myself to stay in the present and take advantage of this year.
Yeah, I haven't had big injuries, but just the wear and tear, and then I think the big thing is -- and I'm definitely still here, which is why I'm back this year -- you have to be all in on this thing. You've got to be locked in. You've got to be obsessed with it. I think when that feeling starts to fade a little but, then it's probably time to go and do something else.
