Between The Posts: Biggest Surprise of 2014?

The Tennessee Titans have been lots of things in 2014; good isnt one of them. That said, I have been thinking about the biggest positives to take away from this year so far (especially in a sea of Titans-related negativity). While I expected Avery Williamson to be good, the rookie ILB has blown away the expectation bar this year. He has been a pleasant surprise this season, along with other young guys like Taylor Lewan (who has outperformed all his linemates), and Zach Mettenberger (thus far).

Who has been the biggest surprise for you this season?
