Anyone who knows Bud Foster is well aware that he's produced one fine defense after another.
Foster's been at head coach Frank Beamer's side since the two worked together at Murray State.
Foster followed Beamer to Tech in 1987 and became his defensive coordinator in 1995.
During the past 13 seasons, the Hokies twice lead the nation in scoring defense, and placed second on three other occasions.
If it wasn't for a few fortunate touchdown passes by Denard Robinson, Foster's defense might have pitched a shutout.
But Michigan's few big plays and Tech's own offensive mistakes allowed the Wolverines to escape with a 23-20 overtime Sugar Bowl victory.
Without further ado, let's check the letter grades of Michigan's unlikely triumph.
