The 20 Best Players to Retire in 2018

3. Jason Witten

Jason Witten was one of the greatest tight ends in the history of the NFL. Witten is second all-time in career receptions and receiving yards by a tight end, only trailing Tony Gonzalez in those categories.

Witten spent his entire career playing for the Dallas Cowboys, where he made 11 Pro Bowls in his 15 seasons. If he wanted to, Witten could still be picking up first downs in the NFL for another 15 years as his running a curl route was impossible to defend.
