The only reason I could see doing anything like this is if at the end of camp, we trade from a position of strength to try to fix a weaker position. If Richards did stand out at LT to the point where he deserved to win that job and we moved Guyton to RT, then trading Steele could be an option to fortify the defensive line, wide receiver, running back, etc. However, I can't see McCarthy wanting a first-year starter and a rookie at the two tackle spots, especially with how much they seem to like Steele and his work ethic.
