Players & difference of opinion

In the second version of ESPNBoston.com's 53-man roster projections, the following players appeared on only one of two rosters:

Mark Anderson -- Veteran defensive end showed up as a pass rusher in the first half of the preseason opener, his strong outside rush leading to Landon Cohen's sack. He could be this year's Tully Banta-Cain, coming on to the field on third down to rush the passer.

Sergio Brown -- Second-year safety spent part of his 2010 rookie season on the practice squad before being promoted. He is a strong special teams player.

Darius Butler -- Third-year cornerback has struggled in camp, but with second-round pick Ras-I Dowling still sidelined, the Patriots might be reluctant to part ways with him at this point.

Mark LeVoir -- Offensive tackle has been with the team since 2008 and the line didn't miss a beat when he was called on to start two games in '08. If the Patriots keep four offensive tackles, he is in competition with first-year player Steve Maneri, who had "more positives than negatives" in the preseason opener, according to Bill Belichick.

Bret Lockett -- Backup safety brings added value on special teams, where he could be a "Big 4" contributor on kickoff returns, punt returns, kickoff coverage and punt coverage.

Steve Maneri -- The Patriots liked Maneri enough to give him a spot on their 53-man roster coming out of training camp last year, claiming him on waivers from the Texans. He's a college tight end who has made the transition to offensive tackle. He played every snap in the preseason opener.

Sammy Morris -- Twelve-year veteran is a versatile option and helps on special teams. But one line of thinking is that a fifth running back is a luxury the Patriots can't afford if they're going to stock up at receiver.

Rich Ohrnberger -- The 2009 fourth-round pick has been working as the backup center behind Dan Koppen. At 6-foot-2 and 300 pounds, he isn't big for the position, but he's a scrappy player.

Gerard Warren -- Now in his 11th season, and second with the Patriots, veteran defensive end offers flexibility with his ability to play 3-4 end while kicking inside to tackle on a more traditional four-man line.

Tracy White -- One of the faster players on the roster, the linebacker finished second on the team in special teams tackles in 2010.
