As the fantasy football season heats up, Monday is the perfect day to scout for potently underrated players who could potentially skyrocket your team to victory. TheScore's Justin Boone highlights key waiver-wire pickups that should be on your radar this week, with specific emphasis on players owned in less than 50% of Yahoo leagues, underlining their Free-Agent Budget (FAB) values based on a $100 cap.

Quarterbacks to Consider:

**Jameis Winston (Browns)** Despite his inconsistent performances, Winston has displayed significant promise since stepping in as the Browns' starter, finishing as a top-12 quarterback in three of his last four games. As he prepares to face Patrick Mahomes this Sunday, he could prove to be a top-level option if wideout Cedric Tillman returns, providing him with additional receiving threats. Although other quarterbacks like Matthew Stafford and Anthony Richardson are over the 50% mark, Winston remains a high-upside pick for fantasy managers looking for QB depth.

Streaming Options:

- **Drake Maye (13% rostered)** at Arizona - **Aaron Rodgers (34% rostered)** at Jacksonville - **Bryce Young (6% rostered)** vs. Dallas - **Cooper Rush (8% rostered)** at Carolina

Running Back Insights:

**Sincere McCormick (Raiders)** Following injuries to starters Alexander Mattison and Zamir White, McCormick has jumped into the spotlight with impressive performances. He's commanded the starting role, notably contributing 89 scrimmage yards last week. Regardless of whether Mattison returns, McCormick's upward trajectory makes him an appealing option, especially with upcoming matchups against less formidable defenses.

Backups with Potential:

Don’t forget about high-upside backups like Blake Corum and Trey Benson, who are only a single injury away from being league-winning players.

Wide Receivers on the Rise:

**Quentin Johnston and Joshua Palmer (Chargers)** With Ladd McConkey sidelined, both Johnston and Palmer stepped up in their last match, creating valuable opportunities in their offense. Johnston's touchdown skills alongside Palmer's reliable targets should place them firmly on your fantasy roster as flexible options, particularly against the Buccaneers.

Tight End Takeaways:

**Juwan Johnson (Saints)** After Taysom Hill’s injury, Johnson seized the chance and delivered with his best game of the season, showing great potential with favorable matchups on the horizon. He could easily serve as a solid TE2 in the playoff stretch, giving fantasy owners a reliable go-to.

Defense Streamers:

Heading into Week 15, consider these defenses with promising matchups: - **Falcons (9% rostered)** vs. Giants - **Packers (37% rostered)** vs. Saints - **Colts (15% rostered)** vs. Titans

Whether you're hunting for a consistent QB, a breakout RB, or a sleeper TE, these picks could be just what you need for a championship run.
