‘BATTLE OF THE WEEK: Fred Jackson vs. Dwayne Wright, Xavier Omon and Bruce Hall at backup RB — This is Jackson’s job to lose behind Marshawn Lynch after his big 2007 season, but Wright and Omon are making things interesting. Each averaged 4.4 yards per carry in last Thursday’s preseason win over Pittsburgh, with Wright ripping off a 16-yard carry and Omon a 14-yarder. Wright hurt his cause, though, with another fumble. Jackson had five carries for 18 yards (3.6 average) and added three catches for 10 yards. Ultimately, the Bills will keep their best athletes at this position and there’s a lot of skill here to mull over.’
