Hard to expect you to be a revisionist historian, Joe. Kendall played LG here for two or three seasons before being switched to center to allegedly extend his career. He stunk as an LG (never got Pro Bowl consideration, never helped lead to a 1000 yard rusher, never lead the offensive line to anything), and was mediocre as a Center. He never even completed 16 games wearing Cardinal red.
As I remember, Kendall had pretty good salaries and signing bonus here. I may be wrong about that, but he was welcomed as the missing piece. This was a while back, when OGs were being paid far less than they are today, of course.
