I think the original poster really means we should trade all of early round picks in an attempt to corner the market on sixth round picks, because that is the round Tom Brady went in. By the OP's single data point logic, Tom Brady going in the 6th proves that 6th round QB's have the same potential to be a Hall of Famer' as early first round QB's.
It will be complicated, but I think if the Bills trade their first round back to some for a first and second, and then trade that first for a second and third and the second for a third and fourth, it will only take 5 transactions (2 ^ 5) to get all thirty two round 6th round picks. Then we just pick every remaining QB in the draft and test them out in spring training. We repeat this process each year until we get the next Tom Brady.

2012 - Smart posters warned everyone else another season of Gailey was a waste of a year. Now we all know
2013 - Smart posters are warning everyone else another year of brandon/nix is a waste of a year. Next year we will all know.
