Pristine one week, penalized the next. The second time around was sloppy for the Cleveland Browns and Detroit Lions. Colt McCoy threw three touchdown passes -- two to tight end Evan Moore -- in the first half, but the Browns blew a 15-point lead after halftime and lost 30-28 to the Lions on Friday night in a penalty-filled exhibition that showed both teams have plenty to fix in the next three weeks before the season opener. "We've got a lot of work to do," McCoy said. "There's plenty to clean up." "Way too sloppy with penalties," said Lions coach Jim Schwartz. McCoy finished 10 of 18 for 96 yards, his second straight solid performance running first-year Browns coach Pat Shurmur's new West Coast offense. McCoy was victimized by a few drops and wasn't as sharp as in last week's win over the Super Bowl champion Green Bay Packers. However, the second-year QB showed poise, ran away from Lions defensive tackle Ndamukong Suh and didn't force any throws while playing most of the first half. "A lot of people wanted to anoint us after last week," said McCoy, who was pressured and knocked down several times. "There were a lot of rough things here and there."
