Nearly every game on the Week 15 NFL schedule has playoff implications, and every one could have an impact on your wallet if you find the value among the many NFL prop bets. Only one game on Sunday's slate features two teams with winning records, but six AFC teams came into the week at 7-6 and five NFC squads are 6-7. The Bengals and Broncos are among those 7-6 AFC teams, and they'll meet in an inter-division game. Which NFL player props should you target?

Green Bay's Aaron Rodgers faces the NFL's second-worst passing defense in Baltimore, and he will be eager to keep the Pack in the running for the NFC's top seed. Caesars Sportsbook lists the Over-Under on Rodgers' passing yards at 274.5 (-115) in its latest Week 15 NFL props. Before locking in any 2021 Week 15 NFL prop bets, you need to check out the top NFL picks and predictions from NFL props expert Alex Selesnick.

Over the past two seasons, Selesnick (aka PropStarz) is up almost 115 units on NFL props and futures plays. For a $100 bettor, that's a more than $11,000 return. PropStarz specializes in NFL and NBA prop betting, where he implements a combination of research, statistical analysis and mathematical modeling.

Through 14 weeks, PropStarz is an impressive 40-29 on his picks for SportsLine after a 5-0 week. In Week 14, he nailed Amon-Ra St. Brown going over 4.5 Receptions (-125) for Detroit, projecting him for six receptions.

PropStarz has touted the receiver as a bright spot for the lowly Lions. With star running back D'Andre Swift and tight end T.J. Hockenson out, the expert expected the wideout to play a big role against the Broncos.

"With Jared Goff struggling to throw the ball downfield, I expect St. Brown to soak up a lot of those targets." PropStarz told SportsLine. He soaked up plenty, catching eight passes for 73 yards in a 38-10 loss to cash this play easily.

Now, after sifting through the hundreds of available Week 15 NFL prop bets, PropStarz has found five more picks he loves. He's only sharing his Week 15 NFL prop picks at SportsLine

Top 2021 Week 15 NFL prop picks

One prop bet that PropStarz loves for NFL Week 15: Bucs tight end Rob Gronkowski to go over 50.5 receiving yards. "Until the books adjust this line, I will happily keep betting on it," the expert told SportsLine. Gronkowski has played seven full games this season and has topped this number in six of them. He also is seeing a 24 percent target rate, higher than the Bucs' dynamic receiving duo of Chris Godwin (21) and Mike Evans (18).

Gronk is clearly quarterback Tom Brady's security blanket, but the future Hall of Famer can still make the big plays. He has a reception of at least 25 yards in four of his seven full games, and New Orleans gives up chunk plays in the passing game. Gronkowski has 498 yards in his seven full games, an average of 71, and is averaging 8.5 targets over the past four games.
