SANTA CLARA ? There is a logical reason cornerback Nate Clements surrendered more than a handful of completions in front of him in the 49ers? first three exhibition games.
Clements said he was merely working on an aspect of his game that he?s determined to improve.
?I?m always trying to work on my weakness,? Clements said Wednesday. ?I know everybody knows me as a physical corner, but I want to work on my weakness because I know my strengths are always going to be there.?
Clements, an eight-year veteran who is the team?s highest-paid player, is known for his bump-and-run coverage and helping out in the run game. But rather than play a physical style of coverage in the exhibition games, Clements has worked on playing off the line of scrimmage.
He yielded three completions on the first drive against the Denver Broncos before intercepting a pass in the end zone. Clements was called for a 22-yard pass interference penalty, then failed to drop deep enough on a 24-yard scoring pass to Raiders rookie receiver Louis Murphy.
Clements was beaten by undrafted rookie Kevin Olgletree on passes of 15 and 21 yards early in the 49ers? game Saturday against the Dallas Cowboys. Patrick Crayton also caught a 19-yard pass on him.
Defensive coordinator Greg Manusky said he is not worried ? yet.
?As long as it is done in the preseason, it is OK and it doesn?t happen in the regular season,? Manusky said. ?He has had a pretty good camp leading up to a couple of those games and having those things happen. You have to keep on working at it and trust his technique and his eyes.?
Clements is not expected to get much playing time Friday night when the 49ers conclude the exhibition season against the San Diego Chargers. But he promises to be up to the challenge when the 49ers open the regular season Sept. 13 against the Arizona Cardinals.
?I?m going to be ready when the season starts,? Clements said.
