"When Greg Jennings is on the field, we definitely have a chance to be a very good offense," McCarthy said. "I still think we can play a different way and play without Greg and still be very good. I'd always want my best players out there. That's why it's important to get him healthy and get him back to 100 percent."
It's possible these Jennings-less Packers are a glimpse into what the offense will look like in 2013. Some believe the Packers will let Jennings walk as an unrestricted free agent after the season because he'll command a contract that will average more than $10 million per season. With quarterback Aaron Rodgers, outside linebacker Clay Matthews and defensive tackle B.J. Raji needing extensions, there might not be enough money to go around.
While frustrated by his injury, Jennings said the contract isn't on his mind.
"Honestly, I'm not even focused on that," he said. "I really need to get back on the football field and be 100 percent. The contract, that's going to take care of itself. It's going to be what it's going to be. I can't predict the future. I couldn't predict this. It is what it is."
