Just barely.
Just barely is the best way to describe Rudolph's quest for the 400 yard passing mark. Coming into what would be his last possession, Rudolph threw a 41-yard pass to David Glidden for a first down, after which J.W. Walsh would finish off the possession with a touchdown.
The funny thing about this game, one in which Rudolph accomplished a feat that few Cowboys had before, is that Rudolph was inaccurate on several passes. Now, few quarterbacks can pass for 400 yards and stay perfect on pass attempts, but in this case, many of the balls Rudolph threw were catchable if thrown only a bit better.
