Scouts Inc.: Tyron Smith No. 2 OL in 2015

The Cowboys believe that Tyron Smith will be an elite left tackle for years to come.

Scouts Inc.'s Matt Williamson agrees. As part of the ESPN Insider future power rankings series, Williamson forecasts Smith to be the NFL's second best offensive lineman in 2015 (when Smith will still be only 25 years old), behind only Miami left tackle Jake Long.

Part of Williamson's take on Smith:

Smith was sensational in his rookie season last year at right tackle. Wisely, the Cowboys will move him to left tackle with Doug Free heading over to the right side. I was tempted to put Smith at the top spot on this list, but after only seeing one season (on the right side), I felt like Long was the safer choice for three years down the road.
