If Caesars sounds like the betting site for you, consider signing up and placing the following wager:

Best Bet: Tennessee Titans -2 (-110) at Pittsburgh Steelers

The Tennessee Titans have played down to inferior teams at times this season, but this matchup feels different. In a game they’ll need to win to maintain their standing among the AFC’s elite, I’m anticipating that the final score will be more lopsided than the spread on our NFL gameday odds would suggest.

As winners of only one of their last five games, the Pittsburgh Steelers appear to be spiraling. Their once-elite defense has given up an average of 34.3 points per game over the last four and has looked particularly terrible against the run as of late.

Even without Derrick Henry, Tennessee should have no issue establishing the run against Pittsburgh’s reeling defense.

The Steelers will fight to stay in this one — their offense tends to shine late when they’re down multiple scores — but I don’t believe they have what it takes to keep up with the Titans, even at home.

TwinSpires NFL Week 15 Bet Promos

TwinSpires Sportsbook may not be as well-known to sports bettors who don’t wager on horseracing, but their welcome bonus is up there with the best. TwinSpires — owned by Churchill Downs Inc. — offers a risk-free first bet of up to $1,000 to new users who sign up today.

Their bonus is quite simple to understand. If your first wager of $1,000 or less is unsuccessful, TwinSpires will return your initial stake in the form of a free bet. Essentially, the sportsbook is granting you another shot at a reward if you don’t win on your first try, which is also explained in Anthony Cervino’s TwinSpires Sportsbook review.

If you’d like to take advantage of this offer, consider pairing it with the following bet for a nice payout:

Best Bet: Total Points Over 50.5 (-109) in Kansas City Chiefs @ Los Angeles Chargers

If you like points, this Thursday Night Football showdown between Patrick Mahomes and Justin Herbert could be the matchup for you.

The Kansas City Chiefs and Los Angeles Chargers aren’t shy about putting points on the board. Each team is averaging exactly 27 points per game on the year (tied for eighth in the NFL), and each has scored 40+ three times.

The factor that could complicate things here is Kansas City’s suddenly stifling defense, which has surrendered just 48 total points over its last five games combined.

That said, divisional games don’t often go by the books. With just one game separating these two teams in the AFC West standings, I’m expecting both to give it their all.

I don’t hate the idea of taking the Under here, but considering the previous meeting between these two produced 54 points, 50.5 seems like a good number to take the Over on for our NFL bet of the day.

If this offer sounds appealing to you, consider signing up and using it on the following bet for NFL Week 15:

Best Bet: Cincinnati Bengals Moneyline (+100) @ Denver Broncos

After losing two in a row at home to the Chargers and San Francisco 49ers, the Cincinnati Bengals will go on the road to take on the Denver Broncos.

Denver has been up and down lately, as their last five games (three wins, two losses) have all been decided by double digits. They’ve been carried by a defense allowing the second-fewest points per game (17.5) in the NFL, which has propped up their sluggish offense.

The Bengals, on the other hand, are winning with offense. They’re averaging the seventh-most points per game this season and feature elite young talent in Joe Burrow, Joe Mixon, and Ja’Marr Chase.

Denver’s beaten similar teams this season, but it feels more likely that Cincinnati edges them out on both sides of the ball and comes away with a road win to solidify their standing in the playoff race.
