I wouldn't rule out Evans actually being an upgrade from Lang. Lang played way up in his contract year, and he has a history of injuries. Evans is 4 years older but without the history of injuries, and he has been a much better player for most of his career. Even last season, he was apparently decent. Drew Brees is nowhere near as mobile as Aaron Rodgers, and the Saints O Line including Evans protected him pretty well. Also, the Saints have been at least average as a running team over his career. If Ted got him for a million or so, I say good going.
tex - the Seattle Seahawks didn't keep him and their offensive line is terrible. He was a stopgap for the Saints as well.
Injuries are one thing, but he isn't close to Lang anymore. He's closer to Taylor's level.
Bud Adams told me the franchise he admired the most was the Kansas City Chiefs. Then he asked for more hookers and blow.
