How well do you know your favorite team’s backup quarterback?

Well, for Buffalo Bills players, coaches and security, that was put to the test when backup QB Case Keenum went undercover at training camp to try to get as many autographs from his teammates without them noticing.

“Most days I’m Josh Allen’s backup. Nobody knows who I am, it’s great,” Keenum said. “So I’m going to see how many autographs I can get from my teammates. Let’s go Bills.”

Keenum used a bucket hat, some shades and a southern twang accent to conceal his true identity.

Bills wide receiver Isaiah McKenzie was the first to get got by Keenum before the backup quarterback got caught trying to get McKenzie for a second autograph.

“Is this Case?!” McKenzie said after signing the football for a second time.

Buffalo wideout Gabe Davis also didn’t notice who Keenum was and even snubbed his teammate’s question, “Who is your favorite backup quarterback?”

But a sporty pat on Davis’ behind gave away that Keenum wasn’t a fan.

Security had no idea who the backup quarterback was and instructed Keenum that his 2019 credential was no longer valid.

Perhaps the hardest teammate to fool was Bills starting QB Josh Allen, who wasn’t having it and immediately recognized the guy he spends the most time with in the quarterback room.

So Arizona Cardinals fans, do you think you would recognize an undercover Colt McCoy?
