GREEN BAY, Wis. – Aaron Rodgers fumbled three times in last Sunday’s loss at Minnesota, and the forecast for this Sunday’s against the Detroit Lions calls for rain. Perhaps that’s why Green Bay Packers coach Mike McCarthy put his team through a wet-ball drill to start practice this week.

Just don’t ask the quarterback if he thinks that will help.

Actually, do ask him, and you’ll find him diametrically opposed to his coach on this one.

“It’s a silly drill,” Rodgers said after Wednesday’s practice. “It’s one of my least favorite drills in the game. I did it today as favor to the coaches because I don’t like that drill because it’s unrealistic.”

Even in a downpour, Rodgers doesn’t think a game ball would be anywhere near as wet as the ones that the Packers submerged in water for Wednesday’s practice.

“If it is an actual rain game, the ball comes into the umpire, he wipes it off and puts it down,” Rodgers said. “You don’t dunk a ball directly in the water and then try to throw it. So yeah, it’s an unrealistic drill, but we do it, and I participated today.

“It’s for everybody, making sure they’re getting used to feeling a ball that’s been submerged in water.”

Rodgers even started his weekly session with the media by apologizing to a reporter for hitting him with an errant pass during practice, and then he made a crack about how "wet balls, they slip around."

Rodgers comments came during an unusually combative session with reporters in which many of the questions were about his struggles and the offensive woes that have the Packers ranked 29th in the league in yards per game.

“They’re frustrating for sure,” Rodgers said. “All of them, I didn’t see anybody coming, but that’s no excuse to have loose ball security. That’s something I’ll make sure I get fixed. If I’ve got to go through the gauntlet at practice, I’ll do that. But yeah, I’ll get that fixed.”

Rodgers’ three-fumble game against the Vikings (he lost one of them) was only the second such game of his NFL career. The other came in the Week 16 loss last season at Arizona.

In all, the Packers fumbled four times in the loss at Minnesota.

"Ball security was definitely not a strength of ours," McCarthy said after the game. "Fundamentals are a huge part of the game, and it’s the difference between winning and losing. We’ll practice it, we’ll emphasize it, we’ll keep emphasizing it and demand it, and the players will demand it and we’ll improve."
