Steelers, Colts, or Patriots, who is most likely going to represent the AFC in the Superbowl?

i think the steelers first. pats second and colts third. the steelers are a team that is already set up right except for oline and on cornerbacks. i think the steelers will be the best because they have young receivers, a great quarterback, great runningback, hall of fame linebackers and safety, great run defense, and they are the best combination for a team. the patriots are good, but they have an average defense and they lack skill in runningback. the colts dont seem to be as good as before because peyton manning is getting older and its taking effect on his career, the runningbacks arent to good, and they are losing key players on defense. the steelers made it to the super bowl with big ben out for 4 weeks and they couldve went 13-3 if ben was in the game vs baltimore in week 4. i think the steelers will take a good cornerback in the draft which should help them in the secondary and the steelers are known to be better than most teams at drafting and scouting. i think the steelers will either get mike pouncey or a cornerback in the first round. if mike isnt there, the best possible cornerback will be picked in the first round for them and that should help them because william gay isnt that good, ike taylor is a good cover corner but hes not good at catching interceptions. and the steelers have a new defensive backs coach who is also a 5 time pro bowl cornerback: carnell lake. with lake teaching polamalu, i think the steelers will be close to unstoppable.
