There are a lot of reasons why college success doesn't always translate to success at the NFL level, and vice versa. Tom Brady is an interesting case because much of his college career at Michigan was spent playing with two other QBs who were also good NFL prospects: Brian Griese (son of former Miami Dolphins QB Bob Griese) and Drew Henson (who also played baseball and was drafted by the New York Yankees).
I just learned about Brady’s two post season bowl victories against Alabama and Arkansas. That’s no small deal...
