When the Detroit Lions moved Michael Williams from tight end to offensive tackle last year, the position switch made a lot of sense. When Williams was first drafted, his blocking ability was viewed as his biggest attribute, and he was really looked at as a potential sixth offensive lineman anyway. Simply moving him to tackle was a sensible progression for his career.
On Thursday, the Lions' decision to move defensive tackle Xavier Proctor to offensive tackle came a bit out of left field. After all, Proctor had spent the last two seasons on the practice squad as a defensive tackle, so why make such a sudden change at this point in his career?
