Those experienced with making NFL picks know that monitoring the weather should be a part of an NFL betting guide. That's especially critical when warm-weathered teams visit cold-climate destinations, and a couple of games you can make Week 15 NFL predictions on stand out in that regard. Raiders vs. Eagles (-11.5) and Dolphins vs. Steelers (-3.5) will see the two Pennsylvania teams hosting, with forecasts calling for freezing temps at the respective kickoffs. Given that, many may see these Week 15 NFL spreads as not being large enough in favor of Philly and Pittsburgh.

Sub-optimal weather often affect player performance, which could have a bearing on Week 15 NFL player props, who you insert into Fantasy football lineups or an NFL DFS strategy. Can you count on the likes of Ashton Jeanty, Brock Bowers, Tua Tagovailoa or Jaylen Waddle this week? If you are looking for NFL picks, NFL parlays, Fantasy football rankings or NFL DFS picks for Week 15, SportsLine has you covered with its proven model, Machine Learning Model and team of experts.

NFL Vegas expert picks revealed 

SportsLine has an expansive team of NFL experts who provide quality betting advice for every game on the schedule. Alex 'PropStarz' Selenick, who is 48-31 (+1104) over his last 79 NFL player props, is backing Patriots TE Hunter Henry Under 42.5 receiving yards (-117) versus Buffalo on Sunday.

"Hunter Henry has been a very reliable target for Drake Maye this season. With that being said, this is a fairly large number for Henry in what I consider a difficult matchup," stated Selesnick. "The Bills defense hasn't performed well and has some major holes, however they cover the middle of field and opposing Tight Ends very well. Buffalo has surrendered the second fewest yards to the position." Selesnick's Week 15 NFL picks can be found here.

Buccaneers vs. Falcons 'Thursday Night Football' picks

A rivalry which is evenly split across 64 all-time matchups, with each team winning 32 times, will be renewed on 'Thursday Night Football'. The Bucs won the Week 1 contest on the road to even the series, and Tampa is a 4.5-point home favorite for TNF. Expert Larry Hartstein, who is 21-11-2 (+848) over his last 34 picks in Atlanta games, is backing the Falcons to cover and leaning Under 44.5.

"Atlanta has won three of the past five meetings; the Bucs' wins came by three and four points," Hartstein said. "Tampa Bay prevailed 23-20 in Atlanta in this year's season opener when Younghoe Koo missed a 44-yard field goal in the final minute. Baker Mayfield continues to play through an injury to his left (non-throwing) shoulder. He's been highly inefficient over his last four games, with four TD passes and four interceptions. While Atlanta got steamrolled by an elite Seahawks team on Sunday, the Bucs are not on that level. Grab the points." Get more 'Thursday Night Football' picks right here.
