The fact that Brady was chosen more than Marino is just the same case as people picking Montana over Marino. People seem to think that a SB is the measure of greatness. Let's see: Doug Williams, Mark Rypien, Steve Young, Joe Namath(pffft), Trent Dilfer, Brad Johnson. All of these guys must be better than Dan too- at least by that logic. The Super Bowl argument is B.S. For it to be true about Montana, it would have to be true also for the other QBs listed above.
The REAL truth is, it takes a TEAM to win a SB and the QBs above(and other QBs that have won) prove it. By your and other peoples logic, all Super Bowl winning QBs would have to be better than Dan Marino. If you (or anyone else who believes that way) say differently, then you(and the rest) are a hypocrite.
