Bills' Case Keenum goes undercover to get teammates' autographs

Bills backup Case Keenum, who signed with Buffalo in the offseason, is not the protypical size for an NFL quarterback. He stands 6-foot-1 and weighs about 215 pounds. In other words, Keenum looks like a regular Joe. By contrast, Buffalo starter Josh Allen stands 6-foot-5 and weighs roughly 250 pounds.

At training camp recently, Keenum went undercover dressed like a fan to see how many autographs he could get from teammates. As part of his "diguise," he wore sunglasses and a scruffy white cap. Hilarity ensued on the video.

"Hey, Isaiah, can I get your autograph, man?" he asked wideout Isaiah McKenzie. "I've been a big fan of yours every since you've been in college." Keenum scored the autograph from McKenzie, who recognized Keenum later when the backup QB asked him to sign his football more legibly.

Later, a security guard caught up with the prankster.

"What are you doing here?" he asked. He apparently had no clue of Keenum's status with the team.

Replied the backup QB: "I'm just trying to get autographs, sir."
The guard shooed Keenum off to another part of the facility.

When Allen made his way to practice, Keenum screamed "Josh! Josh! Josh! You're my favorite player, man."

But Allen quickly caught on to the prank and yukked it up with his backup.

Keenum has played mostly as a backup during his nine-year career in the NFL. Last season, he played sparingly with the Browns. Perhaps his next stop is Comedy Central.
