‘The Bills (2-2) have problems of their own after first-year starter J.P. Losman had a sloppy outing. Buffalo’s 2004 first-round draft pick, Losman finished 11-of-19 for 123 yards, but threw two interceptions and was sacked twice while playing the entire first half. So much for the rhythm coach Mike Mularkey wanted Losman to find in his final tune-up before opening the season hosting Houston on Sept. 11.’
