Herman Edwards is a motivator. He preached the positive to the Jets and they won 10 games with a bunch of confused players trying to figure out why Bill Parcells retired and Bill Belichick didn't take the job as head coach. Looking back, what Edwards did was amazing. He coached a team that was 24th on offense and 28th in run defense to a 9-4 start. A playoff loss to the Raiders ended Edwards and the Jets ride.

Things will be tougher this season, but Edwards will be working with more of his players. He added six starters on defense who he believes better fit his two-deep zone scheme. The key signing was outside linebacker Sam Cowart, who appears to be completely recovered from an Achilles tendon tear. Donnie Abraham and Aaron Beasley replace Aaron Glenn and Marcus Coleman at cornerback. Sam Garnes comes from the Giants as the team's new strong safety. Larry Webster and Josh Evans were added for depth on the defensive line, and Steve White, who knows Edwards from his days in Tampa, will challenge Shaun Ellis for the starting left end job. Edwards knows, though, that the success of his defense is dependent on the play of his defensive line.

The line moves have to be successful to improve the Jets shabby run defense.

The most controversial moves involve the offensive line, which was considered one of the strengths of the Jets the last few seasons. Gone is offensive line coach Bill Muir along with starting right tackle Ryan Young, guard Kerry Jenkins and backup guard David Loverne. Quarterback Vinny Testaverde isn't mobile and relies on the athleticism of the offensive line to protect him. Plus, the Jets offense revolves around the play of halfback Curtis Martin, perhaps the team's most available player.

Man in the spotlight
Wide receiver Santana Moss came to the Jets as one of the quickest receivers in last year's receiver rich draft. Now, it's his time to shine. He's had two knee scopes since being drafted in the first round and caught only two passes last year. The Jets are counting on him to be the receiver with speed downfield and run-after-the catch ability. Laveranues Coles has become an important weapon for Testaverde and Wayne Chrebet is always a favorite target of the quarterback. But for the offense to score more points, they need Moss to be explosive.

Key position battle
Last year's key battle was whether Shane Burton and Steve Martin could come to the team before the start of regular season and make them solid against the run. Martin was solid, but the run defense wasn't. So the key to the season is who does well among four defensive tackles -- Webster, Jason Ferguson, James Reed and the recently signed Evans. Webster and Ferguson are run-stoppers. Reed was a surprise at nose tackle who was the opening day starter because of injuries. The bad news is that Ellis, who is big enough to be the movement tackle, is more of a fit at end and can only help in spots at the critical tackle positions.

Injury update
It may take the Jets a little more time than most teams to get their offense rolling. Testaverde had foot surgery to remove a benign tumor from a bone in his foot. A slice of his hip was used in the bone graft. He is expected to take it easy through the early part of training camp, but he looks fine at minicamp. Center Kevin Mawae, one of the leaders of the offense, won't be available until mid-August because he is coming off rotator cuff surgery. Left tackle Jason Fabini is coming off minor shoulder surgery but will be available at the start of camp. Chrebet had a scoped shoulder that isn't expected to give him any trouble. Cowart hopes to have problems from last year's Achilles tear behind him.

Rookie report
The Jets only had five choices, but they may get significant playing time from their first and last choices. First-round choice Bryan Thomas will press for playing time on a defense that needed upgrades up front. The surprise could be fifth-round choice Jonathan Goodwin who will compete with J.P. Machado for the left guard slot opened by the season-ending injury to Dave Szott.
