Redskins vs. Dolphins Betting Preview Week 6

The Redskins are a surprise -3.5 favorite in Miami this Sunday.  One of these teams will enjoy their first win, barring a tie.  Washington will begin play under new interim coach Bill Callahan.

The Redskins' staggering minus-78 point differential through five games is the worst in the NFC, but it's barely a drop in the bucket compared to the Dolphins' league-worst total of minus-137 -- the lowest mark in NFL history through any team's first four games in a season.

TV: 1 p.m. ET, FOX. LINE: Redskins -3.5. O/U: 41

ABOUT THE REDSKINS (0-5): Washington is expected to begin its new regime under Callahan by going back to quarterback Case Keenum, who fared well in his first two games before being responsible for six turnovers in his last six quarters over his final two. A foot injury prevented Keenum from getting the nod in last week's 33-7 setback to the Patriots, a game in which Colt McCoy was sacked seven times and threw an interception. Although versatile Chris Thompson leads the team with 25 receptions, Callahan wants to see the offense commit "a little more" to the 27th-ranked ground game (68.8 yards per game). "I think a running back needs to get into a rhythm, and we've got to find a run rhythm," Callahan said of using both Peterson and Thompson. "I can't guarantee or promise that'll happen, but that's the goal to find a rhythm where we can get these backs rolling and going."

ABOUT THE DOLPHINS (0-4): With whispers of "Tank for Tua" growing louder following each loss, Josh Rosen finds himself in an all-too-familiar place despite being named the starter for the rest of the season for a team that is "contending" for the top overall pick of the 2020 NFL Draft. "If I play well enough over these 12 (games), hopefully they'll make the decision. I mean, technically, it's never over, essentially," said Rosen, who was the odd man out in Arizona after the Cardinals selected fellow quarterback Kyler Murray with the first overall pick of the 2019 draft. Rosen tossed a 34-yard touchdown pass last week to Devante Parker, who had a season-high four catches for 70 yards against the Chargers. Parker's 201 receiving yards are tied for the team lead with rookie wideout Preston Williams, who has recorded four catches in each of the last three games.
