Joe Callahan is ready to go if needed (as if he’d have a choice)

From the moment Packers coach Mike McCarthy barked “did you just listen to the question I just answered?” at a reporter who had the nerve to ask whether Colin Kaepernick could be added to the post-Aaron Rodgers quarterback depth chart, one thing became clear: Former Division III quarterback Joe Callahan would be one injury to Brett Hundley away from becoming either a disaster or a Disney movie.

More than a month later, the possibility that the guy we’ve jokingly been calling the wrong name (primarily Houlihan) due to his anonymity. As it turns out, Callahan also is known by multiple other names within his own locker room.

Via Jason Wilde of the Wisconsin State Journal, the options have includedBig Tom Callahan’s Son” (a Tommy Boy pull), “Bo” (after the quarterback whose draft stock falls in Draft Day a/k/a The Worst Football Movie Ever Made Not Named Leatherheads), “Francis” (his actual first name), and “Joseph-Joseph” (due to confusion by one of the assistant coaches when Callahan said his middle name is Joseph).

By whatever name, Callahan could be getting the same kind of baptism by blast furnace that DeShone Kizer received back in Week One.

“You know, I feel good. It’s my second year in the offense, and the past couple weeks I’ve really been in tune with the game plan,” Callahan said, via Wilde. “If anything were to happen, I’m ready to go. I’m preparing like I’m one play away.”

If a change happens, it will most likely occur due only to injury. McCarthy has given no indication that he’s thinking about benching Brett Hundley, even after a home shutout loss to the Ravens last weekend. Still, McCarthy apparently would be comfortable putting Bo Francis Joey Joe Joe Houlihan on the field, if need be.

“If you’d have seen the team drills [the other] day, he had three big-time go-route balls — deep, deep balls,” McCarthy said. “Clearly I think Joe’s deep ball has gotten a lot better throughout the year. He’s comfortable running the offense, does a great job running the opponent stuff, so he’s definitely progressed.”

But has he progressed to the point where he could step in and play at Heinz Field? Against the Steelers? In prime time?

In an intriguing story line in a game that, due to the absence of Rodgers, could use one.
