he's 10x better than Favre, who set the record for most ever interceptions with that amazing arm of his
Brady had a very strong arm, but maybe not elite arm strength... although thats debatable, when you're just trying to compare him to a gunslinger like Favre as the bar for whether someone has a great arm or not
its not a very important factor for QB play, it comes in handy on occasion but as long as you have an above average arm strength its more about accuracy, anticipation, pocket presence, reading defenses, etc.. basically as long as you dont have a chad pennington or mac jones level of arm strength, it doesnt matter
JaMarcus Russel had a monster arm, but he was total dog shit
