Arizona Cardinals backup quarterback Mike Glennon comes into the 2018 season what his role is expected to be. It is not to be the starting quarterback. It is a role he is familiar with, although he still has the mentality that he is talented enough to be a starter.

He has backed up some notable players. In college, he was Rusell Wilson’s backup. After starting as a rookie with the Tampa Bay Buccaneers, he backed up Josh McCown and then Jameis Winston. Then, after being pegged as the starter for the Chicago Bears, signing a big free agent contract, he was relegated to the bench after four starts to let No. 2 overall pick Mitchell Trubisky take over.

He keeps things in perspective.

“Everyone wants to be out there playing, but at quarterback it’s a unique situation because only one guy can play,” Glennon said, according to AZCardinals.com’s Kyle Odegard. “That dates back to my time in college when I was behind Russell Wilson (at North Carolina State) for three years. You feel like you’re a pretty good player yourself, but there’s only room for one guy. You just have to keep everything in perspective and realize I’m still living the dream.”

Now behind Sam Bradford and perhaps 10th overall pick Josh Rosen, Glennon knows his place.

“I’ve been in that backup role more than the starter, so I’m comfortable with it,” Glennon said. “I understand my role, and what my job is to help this team. That’s to both compete and help these two guys out.”

While Glennon most certainly would like a starting job, he might have found the perfect role for himself. At age 28, he could very well become the new version of Drew Stanton, who backed up Carson Palmer for five seasons. He was great in the classroom and the locker room. He had the same respect of his teammates. He even won a few games as a starter in Palmer’s absence the seasons Palmer landed on injured reserve.

He very well might be the No. 3 QB this season. However, he will most certainly be the No. 2 QB in 2019 when Rosen is expected to take over. And if he wants a stable place the rest of his career, he very well could fill that role for another half decade at least.
