Joe Flacco is gaining more comfort in Gary Kubiak's offense.

The Baltimore Ravens hired Kubiak as offensive coordinator in the offseason to replace Jim Caldwell.

"I've been able to get really, really comfortable and kind of just get back there, go through my reads, and have a lot of fun," Flacco said. "I think we look good; it's been a lot of fun. Like I said, I think everybody has put a lot of hard work in, and because of that we've been able to go out there and work on some of the little things and really get better." 

Flacco has been asked to do things this year that he hasn't done on the Ravens practice field previously. There has been cone drills to help improve his footwork. There have been ball security drills where coaches have hit Flacco's hands with blocking pads. Fundamentals have been a major focus. 

"At this stage, he's playing very well," coach John Harbaugh said. "I would love to see him against another defense today. If we were allowed to scrimmage somebody, we'd have a scrimmage out here and we'd know more, but he looks good."
