The best the first 30 minutes had to offer was a strong performance by Buster Davis, who was targeted five times and caught four passes for a team-high 82 yards. Davis actually caught the fifth pass, too, but was unable to get both feet down in bounds.
While Chargers fans are excited to see Davis looking ready to contribute -- which will be needed, given the absence of Vincent Jackson -- the real story on Thursday came in the second half when fringe players fought for their NFL lives.
FB Mike Tolbert
Williams sparked a Chargers rally by returning a punt 93 yards for a score. He also caught four passes for 42 yards. Although his stellar night was tarnished by a lost fumble in the fourth quarter, he likely solidified his place on the active roster.
Brinkley's future is less certain, although he did himself a world of good at Candlestick Park. The first-year back gained 100 yards from scrimmage on only 18 touches (13 rushes for 57 yards; five receptions for 43 yards). Nonetheless, he may be expendable because of the presence of versatile FBs Mike Tolbert and Jacob Hester.
Also helping himself was Jonathan Crompton, who played the entire second half and completed 9-of-16 passes for 114 yards and an interception. With the Chargers considering keeping only two QBs on the active roster this season, Crompton stepped up and may have preserved his position among the final 53.
Williams, Brinkley, Crompton and the rest of the fringe players will learn their fate on Saturday, Sept. 4, when the roster must be reduced to 53 players.
