His point is the Lions could have a hole at either RT or LT with Sewell being able to play both at a high level. They could have easily kept Sewell at RT where he has been playing at an elite level and draft Freeling to be their LT. It almost makes more sense. I also think painting these players into traditional LT or RT roles by their style is a little outdated. With the way defenses are moving their DL and pass rushers around the RT needs to be just as quick at the LT anymore. OG play is even considered more valuable now that it was in the past.
