OAKLAND, Calif. -- A look at some of the positive and negative performances from the New York Jets' 45-20 loss to the Oakland Raiders:

THREE DOWN

PR Kalif Raymond: He made the single-biggest mistake of the game, muffing a punt at his own 4-yard line just before halftime. Talk about a momentum killer. The Jets had just forced a three-and-out after closing to within 14-10. Instead of going into their two-minute offense, the defense was back on a short field. The Raiders wound up scoring -- a gift touchdown -- to make it 21-10. Afterward, Raymond owned up to it, saying it was just a lack of concentration. He actually said it was his easiest chance of the day. The recent waiver-wire pickup has three muffs in two games. Coach Todd Bowles expressed frustration, meaning Raymond could be on thin ice. The Jets aren't good enough to be giving away points.

CB Juston Burris: He was involved in three of the six touchdowns allowed. Burris got beat by Michael Crabtree on two of the receiver's three receiving touchdowns (including a 26-yarder in which he showed no ball awareness), and he also was badly faked on Cordarrelle Patterson's 43-yard scoring run. Burris has talent, but he has to play with flawless technique because he lacks ideal catch-up speed. This wasn't a good game.

ILBs Demario Davis/Darron Lee: When a team allows 370 rushing yards in two games, it's not a ringing endorsement of the two men in the middle. They tend to overpursue, getting caught out of position. On Patterson's long touchdown, both Davis and Lee were blown out of the A gaps by interior offensive linemen, leaving a huge hole for the runner. Later, on Jalen Richard's 52-yard touchdown run, Lee was neutralized on a kick-out block. Maybe they miss David Harris' steadiness in the heart of the defense.

THREE UP

WR Jermaine Kearse: He was a good pick-up in the Sheldon Richardson trade. After two games, Kearse is by far their best receiver (team-high 11 catches). He's also the only wideout averaging at least 10 yards per catch (11.2). (Has anybody heard from Robby Anderson?) Kearse scored his first two touchdowns as a Jet, displaying a nice chemistry with Josh McCown. His 34-yard touchdown came on a third-and-2, a situation they anticipated in practice. After a conservative passing attack in Week 1, offensive coordinator John Morton told the players they'd be aggressive, especially if they got tight-man coverage. According to McCown, Morton said, "We're not going to play scared." They certainly didn't in that situation.

QB Josh McCown: He has only 353 passing yards in two games -- heck, Tom Brady blew that away in one afternoon -- but McCown is going a nice job of managing the offense. He threw two touchdowns, committed only one turnover (a strip sack on a safety blitz) and showed that a man with 38-year-old wheels still can move. He scampered for a 22-yard scramble, the Jets' longest run of the day. It actually came on the dirt portion of the baseball field at Oakland Alameda-Coliseum. "I wasn't much of a base stealer in Little League," he said, "but there I was, on dirt."

CB Morris Claiborne: He covered Amari Cooper most of the day and held him to four catches for 33 yards. Claiborne, good when he's healthy, also had a pass break-up and a tackle-for-loss.
