FOXSports.com senior NFL writer Alex Marvez weighs in with NFL news and notes  every Monday

* Know why Joey Porter hasn’t made an impact with Miami?

He needs help from three others to beat a left tackle.

Porter’s disastrous 2007 season reached a new low Sunday. He was exposed as a thug by my FOX Sports colleague Jay Glazer, who unveiled a videotape showing Porter and his buddies jumping Cincinnati left tackle Levi Jones at a Las Vegas casino in March. Porter then floundered in a 41-31 loss to Cleveland, tallying a meager four tackles.

Porter ran his mouth beforehand by again picking on Browns tight end Kellen Winslow, who he slurred with a homosexual innuendo last season while playing for Pittsburgh. Winslow finished with five catches for 90 yards and asked reporters afterward, “Did he play today? I didn't see him.”

Before games against Dallas and Oakland, Porter called Cowboys running back Marion Barber “cocky” and guaranteed a win against the Raiders. Barber rushed for two touchdowns in a Cowboys rout, while Oakland cruised to a 35-17 victory. Porter made no impact plays in those games and hasn’t registered a sack in Miami’s 0-6 season.

Still, nothing was as humiliating as Glazer’s expose. Details of the Porter-Jones altercation were fuzzy because of a shoddy police investigation, as the two were reported to have fought in a valet parking area. Porter was fined $1,000 in May after pleading no contest to misdemeanor battery.

The NFL then fined Porter three game checks, which is the equivalent of roughly $141,000. But the punishment would probably have been more severe had the video footage surfaced earlier.

Having landed a five-year, $32 million contract with $20 million guaranteed, Porter is this season’s biggest free-agent bust (although Denver running back Travis Henry is a contender if suspended because of drug issues). Compounding the problem, Miami offered an Adalius Thomas-sized deal even though no other suitors were going to offer the same cash for a fading eight-year veteran.

The only positive from this: The season-finale between Miami and Cincinnati (1-4) now has additional meaning besides being a potential duel for the 2008 draft’s No. 1 pick.

* Another suspect Dolphins free-agent decision was allowing punter Donnie Jones to join St. Louis as a restricted free agent. Jones and San Francisco’s Andy Lee are tied for the NFL lead in gross average at 50.1 yards. Jones also has an impressive net average of 42.0.

In comparison, Miami rookie punter Brandon Fields has averages of 43.0 and 36.3.

“I just think it’s getting a fresh start and having some extra motivation being in a new place with a new staff,” said Jones, who clashed this off-season with Miami’s new kicking coach. “It’s a very good work environment and our special teams coach Al Roberts is a tremendous guy. He lets me go out and do my thing.”

* Dallas Cowboys executive Stephen Jones waited outside the locker room to congratulate New England owner Bob Kraft following the Patriots’ 48-27 victory.

“Y’all taught us a lesson,” Jones said.

A much less classy move came from another Jones. During a Sunday night pay-per-view wrestling match, suspended Tennessee cornerback Adam “Pacman” Jones threw money into the ring to distract his team’s opponent. The move was meant to spoof Jones “making it rain” earlier this year at a Las Vegas strip club.

Considering a club manager was shot and paralyzed later that night after a blow-up with Jones’ entourage, how can anyone think this would be funny?
