Aaron Rodgers spoke out on Tuesday about the effort of the Green Bay Packers' young receivers during practice.

"I think it was one of the worst carded sessions we've had," Rodgers said. "I don't know how you can make it simpler. You literally have what the play would be in our terminology of the card. And the effort level was very low, especially what I'm accustomed to, having run that period for a number of years. It's not a good start for us on the carded period for the young guys. I think [DeAngelo] Yancey has really progressed, [Geronimo Allison], obviously 16 [Jake Kumerow]. But everybody else was piss poor."

Rodgers has been candid as of late. He expressed displeasure over the departure of Jordy Nelson and the fact that he hasn't finalized a contract extension.
