Montana actually threw touchdowns at a higher rate then Favre Threw more yard's per pass, completed passes more often and threw INTs less often.
Favre played a lot more games. You're comparing their stats as if they played the same amount. Everyone (except you apparently) knows one of the reasons Favre has things like the all time TD record is because of longevity. Favre threw nearly twice as many passes as Montana. It's the reason Manning is on pace to break that record in fewer games, and is on record to do it w/o breaking the alltime INT record (which Favre also holds).
Good job good effort.
