Do the Dallas Cowboys still have a shot at the playoffs?

The Cowboys have been on a winning streak since coach Jason Garret took over for Wade Phillips, they beat the Giants and today or since its midnight yesterday the Lions,they are 3-7. My question is,is there any possibility they can still make it to the playoffs? I mean its a very long shot but in the NFL you never know especially once its battle for the wild card? If they win all there games the rest of a season can they at least make the wild card? and please be honest and no hating if your not a cowboy fan that is just gonna write hateful comments then don't even bother, im looking for someone who can actually give me a legit answer and knows football and the possibility's...this is a once in a million chance for the cowboys to actually play in the Superbowl in there own stadium..so im sure now with a new coach they want to aim for that....
