Last year's playing weight listed at 296 (miamidolphins.com). Seems as though our boy has gained 20 pounds (hopefully all muscle) and is at about 315 as of now.

Second-year LT Wade Smith has bulked up to about 315 pounds by diligently following a workout regimen. Last season, Smith played very well considering he was a third-round pick, though he was overwhelmed against elite ends. Smith is bright, dedicated and mature. He works relentlessly and doesn't lose confidence in tough times.
