May 13 (UPI) -- Denver Broncos signal-caller Joe Flacco said it isn't his responsibility to develop rookie quarterback and potential successor Drew Lock.
"Listen, I have so many things to worry about. I'm trying to go out there and play good football. I'm trying to go out there and play the best football of my life," Flacco told reporters Monday. "As far as a time constraint, and all that stuff, I'm not worried about developing guys or any of that. That is what it is. And like I said, I hope he does develop.
