The Dallas Cowboys have been looking for a new go-to receiver this season, and Jerry Jones went all-in on Amari Cooper in a trade with the Raiders. They'll get their first chance to see their crown jewel on Monday Night Football against the Tennessee Titans at 8:15 p.m. ET at AT&T Stadium. Dallas opened as a 4.5-point home favorite in the final game of Week 9, but is -5 in the latest Titans vs. Cowboys odds. In this battle of top-five scoring defenses, Vegas has set the Over-Under for total points at just 40, down two from the opening line and the second-lowest of the week. With both teams looking for a strong second-half run to overcome middling starts, be sure to check out the latest Titans vs. Cowboys picks from SportsLine's Mike Tierney. 

Tierney is a veteran national sportswriter who has emerged as the top NFL expert for SportsLine. He enters Week 9 of the NFL season on a blistering 31-11 run on all his NFL picks, returning almost $2,000 to $100 bettors during that span. He also has a keen eye for when to back and when to fade Dallas, evidenced by his strong 17-8 run on all his picks involving the Cowboys.

The last time the Cowboys played at home, Tierney picked Dallas (+3.5) for a matchup against the Jaguars. The result: Dallas not only covered, but exploded for a 40-7 outright win that covered the spread with an unthinkable amount of room to spare.

Now he has zeroed in on Cowboys vs. Titans and locked in another strong play over at SportsLine. 

Tierney has considered the ramifications of Cooper's addition to the Cowboys' offense. The Cowboys have struggled to consistently move the ball this year, with no receiver managing to record more than 40 catches or 350 total yards through seven games.

Cooper, who had two 1,000-yard campaigns in three full seasons in Oakland, adds a new dimension for quarterback Dak Prescott and the offense. His presence should relieve some stress for Ezekiel Elliott and the run game as well. Even a modest improvement to the offense could be a difference-maker for a Dallas team that boasts the No. 2 scoring defense in the league.

But just because the Cowboys made a big splash in recent weeks doesn't mean they'll cover the spread against Tennessee.

The Titans haven't always put an impressive product on the field this year, but they specialize in keeping games competitive. Six of Tennessee's seven games have been decided by seven points or fewer, with five coming down to a field goal or less. They've lost two games all season (Dolphins, Ravens) by more than five points, the line for Monday Night Football. Similarly, the Cowboys have only beaten two teams this season (Giants, Jaguars) by more than five points. 

A diverse rushing attack that features running backs Dion Lewis and Derrick Henry combined with the feet of quarterback Marcus Mariota keeps the Titans in games, while their bend-but-don't-break defense is giving up just 18.1 points per contest.

We can tell you Tierney is leaning toward the over, but his much stronger play is on the side. He has identified an alarming trend that makes one side of the spread a must-back. He's sharing what it is, and who to back, only at SportsLine.
