Man we can agree to disagree. When people talk about QB's and let's say the hall of fame they talk championships. How many qb's are in the HoF that don't have a championship, if there are any I would bet that number is small. Brady owns the majority of QB records what other measuring stick can there be?
We could also say situation dictates the success of a QB. How many were placed in bad systems?
What about different eras?
There are so many variables but the typical deciding factor is statistics and Brady has most of them.
