retired or active.

answer is Warren Moon with 161 career fumbles

Grossman will break the record eventually if Lovie Smith keeps playing him. Kurt Warner has a lot of fumbles. The all time leader is Warren Moon. He had 161 fumbles as a QB playing from 1984-2000. In second is Dave Krieg with 153 and in third is the still active Brett Favre with 138. You would think Moon would be a awful player but he is actually a nine time Pro Bowler.

um i dono

Rex Grossman?

He hasn't been at it long, but I think Rex Grossman is making a case for the record.

Last year Jon Kitna had the most for the season. All time, I don't know.

Most fumbles, career: 161, Warren Moon. and thats the record all-time!

As far as active it has to be Rex Grossman, as much as he fumbles you would think the football is burning hot. Jake Delhomme is a close second.

i don't know

Are you serious? Warren Moon was one of the greatest ever. I'm assuming you're talking about the one who played for the Oilers/Titans but I was going to say Rex Grossman.
