Who is your dark horse team to make the playoffs this year in the NFL and why?

i'm going with the detroit lions, Thier O looks unstoppable with a healthy Stafford in there and there D line of course, also the secondary has a healthy Louis Delmas back. And with free agency still to go if they land a decent CB or LB the D will be much improved as well. also this team beat the superbowl champs with a 3rd string qb and lost by 2 with their 2nd string in and should of beat the NFC north champs in the 1st game and a questionable call on Suh could have cost the lions the 2nd game as well.
