There are several key divisional matchups on the Week 13 NFL schedule, and there are 12 games on the Sunday slate. There are dozens of NFL prop bets available in each matchup, and weather, injuries and teams' motivation can all play a role in whether you win or lose. Some teams are desperate to get back into the NFL playoff picture, including the Broncos (6-5) in an NFC West battle at Kansas City (7-4). The Steelers (5-5-1) are trying to claw their way back when they host AFC North leader Baltimore (8-3), and the 49ers (6-5) are seeking their fourth straight victory when they play Seattle (3-8).

Baltimore's Lamar Jackson has had to play dual roles this season after injuries ravaged the Ravens' backfield. Caesars Sportsbook lists the Over-Under on Jackson's passing yards at 234.5 in its latest NFL props, while he is favored to go Under 65.5 rushing yards (-125) in the Week 13 NFL player props. Before locking in any 2021 Week 13 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 124 units on NFL props and futures plays. For a $100 bettor, that's a more than $12,000 return. PropStarz specializes in NFL and NBA prop betting, where he implements a combination of research, statistical analysis and mathematical modeling. 

Through 12 weeks, PropStarz is an astounding 35-25 on his picks for SportsLine. He nailed all five picks in Week 12, and most of the picks weren't really in doubt.

Jaguars tight end Dan Arnold went well under 4.5 receptions (-115), with just one catch for nine yards, although he was injured in that game. Ryan Tannehill threw for just 93, well under the 225.5 (-115) Caesars set as the over-under for the Titans quarterback's passing yards.

And PropStarz was right on the money when he called for Bucs tight end Rob Gronkowski to go over 3.5 receptions (-115). "Gronk should have no problem clearing this total," he told SportsLine, citing the Colts' poor performance against tight ends and the likelihood it would be a high-scoring game.

All Gronkowski did was catch seven balls for a season-high 123 yards in Tampa Bay's 38-31 comeback win against Indianapolis. Anyone who has followed PropStarz this season has cashed in big.

Now, after sifting through the hundreds of available Week 13 NFL prop bets, PropStarz has found five more picks he loves. He's only sharing his Week 13 NFL prop picks at SportsLine

Top 2021 Week 13 NFL prop picks

One prop bet that PropStarz loves for NFL Week 13 is Seattle receiver Tyler Lockett going under 5.5 receptions (-150). Seattle quarterback Russell Wilson hasn't been the same since returning from a finger surgery, and Lockett isn't having the same success he had last season. The seventh-year man had 100 receptions in 2020, but he has just 50 so far this season and has had more than five catches in a game just twice. He hasn't topped four in the past three games.

Lockett has been targeted 18 times and has nine catches since Wilson's return, and Seattle's quarterback has completed fewer than 56 percent of his passes in the those games. Lockett's role as a deep threat and the Seahawks' difficulty controlling the ball have limited his chances. The Seahawks are last in the league in time of possession, while the 49ers are ninth. PropStarz is predicting that Lockett will have four receptions.
