AFC East Stock Market: Week 5

The NFL regular season is more volatile on a week-to-week basis than the Stock Market. A team that lost by several touchdowns the week before can follow up with a blowout victory. Players who are responsible for the blame one week could be responsible for a game-winning play the next.

With Week 4 of the regular season in the books, let's take a look at three AFC East players who saw their stock rise, and three AFC East players who saw it fall.

Chris Ivory, running back, New York Jets

No player had more rushing yards than Chris Ivory in Week 4. Ivory racked up 166 yards on the ground against the Miami Dolphins in London on Sunday and proved his value to the New York Jets. He's the definition of a workhorse back as he carried the ball 29 times and took pressure off of quarterback Ryan Fitzpatrick and the aerial attack. The offense will go as Ivory goes.

Charles Clay, tight end, Buffalo Bills

Not much went right for the Buffalo Bills on offense in Week 4, but Charles Clay was a bright spot. Against the New York Giants in Week 4, Clay caught a career-high nine passes for 111 yards, and he was Tyrod Taylor's favorite target with Sammy Watkins sidelined. He'll look to continue the upward trend against the Tennessee Titans in Week 5.

Brandon Marshall, wide receiver, New York Jets

Brandon Marshall has flown under the radar as one of the best wideouts in the league on a Jets offense that doesn't get much attention. He's quietly ranked sixth in the NFL in receiving yards with 400 after racking up seven catches and 128 yards on Sunday. He's Fitzpatrick's go-to guy and rightfully so. Marshall has returned to form as a true No. 1 threat.

Ryan Tannehill, quarterback, Miami Dolphins

The Dolphins have issues on both sides of the ball, but Ryan Tannehill is expected to be a consistent threat at quarterback. In Week 4, he was hardly that. Tannehill completed just 43 percent of his passes for 198 yards and two interceptions. He constantly looked uncomfortable in the pocket and hasn't been the answer for the offense over the past two weeks. A Week 5 bye could change that and help the young quarterback.

Cameron Wake, defensive end, Miami Dolphins

Another game, another goose egg in the sack column for Cameron Wake. Through four games, Wake has made very little impact for the Dolphins as he has yet to record a sack. Additionally, he only has one tackle and one quarterback hit, which isn't what the Dolphins were looking for from their stud pass rusher. He's not the only problem in Miami, but he needs to start getting pressure if the Dolphins hope to fix the defense.

Jeff Cumberland, tight end, New York Jets

It hasn't been a good season for Jets tight ends, and it all started with Jace Amaro going down with a season-ending injury in training camp. In his absence, Jeff Cumberland has stepped in and been largely ineffective. That trend continued in Week 4 as he had his second game without a catch, and he has just two receptions in three games played. Cumberland's disappearance is concerning.
