ENGLEWOOD, Colo. (AP) -- Montee Ball was known at Wisconsin as a reliable, durable running back, not a fumbler. In 924 carries he coughed it up just twice, and one of those came when he was knocked cold.
So, when he matched that total in the NFL in just 31 carries, alarm bells went off around Denver Broncos headquarters.
Running backs coach Eric Studesville soon found the flaw and offered a subtle solution: tucking the football into the crook of his elbow a split-second faster.
Ball hasn't put the ball on the ground since.
