Joe Montana Won't Say Tom Brady's The Best QB Ever

Joe Montana was asked point-blank if 5-time Super Bowl winner Tom Brady has finally surpassed him as the greatest QB of all time.

He won't say "Yes."

The 49ers legend appeared on "Home & Family" on the Hallmark Channel (airs Friday) with his wife Jennifer ... when they got into one of big sports topics of the week -- Montana vs. Brady.

The hosts even pressed and asked Joe if he considered HIMSELF the #1 QB ever -- to which he replied:

"Even though people say it -- and I appreciate it -- I still can't say that about myself."

That's when Jennifer came through with this gem -- "At home you're saying that all the time!!"
