QB Joe Flacco's 2011 season had its ups and downs, with flashes of brilliance intertwining with head-scratching moments. 
Part of the problem could've been the lack of time spent with his new receivers due to the NFL lockout. Regardless, Flacco had his lowest completion percentage (57.6 percent) of his career last season. 
"We didn't, as a unit, execute the way we needed to (in 2011), and we have addressed that this whole offseason," said offensive coordinator Cam Cameron. "I think our guys are committed to making sure our offensive completion percentage is where we want it to be."
Flacco's looked sharp in training camp, and the offensive coaches have been impressed with his preparation. Cameron said it's typical to shoot for a 70 percent completion percentage each season.
Flacco's best completion rate was 63.1 percent in 2009. Drew Brees set the NFL record in 2011 with a 71.2 percent completion percentage. 
Other notes: LT Bryant McKinnie missed his third day of training camp. It's unclear when he'll decide to report. 
CB Jimmy Smith left practice Saturday after an apparent injury. Defensive coordinator Dean Pees said it happened during a special teams drill. Smith's injury doesn't appear to be major as he was seen walking without a limp after practice.
Billy Cundiff missed his first kick of the preseason, a 48-yarder that went wide left. He did make a 55-yarder Saturday. Rookie Justin Tucker is 20 of 20 in training camp. 
CB Lardarius Webb (personal) returned to practice Saturday. Not participating in practice were DT Haloti Ngata (hamstring), WR David Reed (ACL), G Justin Boren (undisclosed), T Ramon Harewood (ankle), G/T Jah Reid (calf) and DE Pernell McPhee (knee). 
The play of the day came from backup QB Tyrod Taylor, who heaved what looked to be a 60-yard pass to WR LaQuan Williams for a touchdown.
