The Cowboys have more than enough on their plate as they try to work towards extending some of their biggest contributors. Searching for a swing tackle may not be as high on their offseason checklist but it’s still important when you consider the punishment of the position. Tyron Smith and La’el Collins are both guys that often play through the pain but there have been several occasions in the past couple of seasons when Smith was out of the lineup. In the NFL, you should always have a contingency plan in place, which means swing tackle is an underrated, but crucial, part of the Cowboys depth chart.
