General manager Jerry Angelo said the Bears search for a veteran backup was concentrated on quarterbacks who had played in Mike Martz's offense.
"Given where we were, with five games left, we wanted to get somebody who had familiarity," Angelo told the Sun-Times. "We're training a new quarterback in Caleb [Hanie]. You know there are going to be some nuances to that, and adjusting to him."
So while Brett Favre and Donovan McNabb were the most prominent names out there, the Bears instead reached out to those who had played for Martz before.
Shortly after starter Jay Cutler suffered a fractured thumb in his right hand, the Bears evaluated their quarterback options. Hanie, of course, was handed the starting job, but the club wanted a veteran so they didn't have to turn to rookie Nathan Enderle.
"We wanted to minimize every speed bump," Angelo said.
The reality is, because Hanie got so few snaps behind Cutler, Martz wasn't going to have time to work with a player unfamiliar with his scheme. So Hanie would have to take every possible snap and whoever would back him up wouldn't get any, thus the focus on veterans who had played for Martz before.
They reached out to J.T. O'Sullivan, Josh McCown and Marc Bulger, who reiterated that he's happily retired.
The Bears then signed McCown. Today, against the Denver Broncos, he'll be the back up to Hanie. He was the third quarterback the previous two games.
