Shirtless Troy Aikman could tempt Cowboys to bring him back — as linebacker

Troy Aikman looks like he still could play for the Dallas Cowboys. At linebacker even.

The 49-year-old Hall of Famer was spotted jogging shirtless in Hawaii this week, and showing off a mean eight-pack:

We haven't seen a beefcake QB like this since shrtless Tebow in the rain. And Tim was half Troy's age at the time!

Shoot, Troy looks better now than he did when he was 25.
