Every now and then, Brady Quinn flirts with getting on the field for a regular season game.
Still, it hasn't happened since 2009.
The backup quarterback for the Kansas City Chiefs is in waiting after a tumultuous start to the season by starter Matt Cassel.
In his eighth season, Cassel has 10 of the Chiefs' 15 turnovers. A team that was touted to be in playoff contention has lost three of their first four games and is on the verge of a meltdown.
Quinn, who spent the last two seasons with the Denver Broncos, was a 2007 first-round draft pick of the Cleveland Browns. He last played in a regular season game against the Chiefs.
"My job hasn't changed," Quinn told the Kansas City Star. "I still go out there and support Matt and the rest of our teammates. We've got a lot of things that we've got to get better on. As a whole, as a team, weve got to play better complementary football.
"The only thing that changes is when you have an opportunity to go in and play. Besides that, everything is as-is. We continue to work hard, we continue to support each other and stick in our role."
Ravens coach John Harbaugh contends he has contingency plans in case Quinn gets the call. With the Browns, he was an AFC North foe.
"You always look at the backup quarterback. You've got to know who the backups are and what their strengths are," Harbaugh said. "We've played against Brady, and we know how talented he is. But Matt Cassel is not to be underestimated by any stretch. He's put together great seasons, he's put together great games. He knows that offense, that New England-style offense that they run there. He's got all the ability, and we're going to deal with Matt Cassel - that's the starter."
