More Top 2025 Best Ball Stacks

An increasingly popular strategy — and perhaps a necessary one — in best ball fantasy football tournaments is to “stack” several players on the same team. The benefit is twofold: that teams’ offensive “spike weeks” will result in amplified scoring for their fantasy players, and you won’t need to get nearly as many things right when drafting. You can take advantage of being correct about a specific offense in a given week or season, instead of needing to be accurate about multiple different players around the league.

This strategy was implemented by last year’s Underdog Fantasy Best Vall Mania V Winner, who drafted both a Bengals and a 49ers team stack, which rewarded him with a $1.5 million payout. I’ll provide several teams that I believe have tournament-winning upside in Best Ball Mania VI.

UD-Points aka “Underdog Points” are half PPR fantasy points

Total Spike Weeks by Position in 2024

San Francisco 49ers

Brock Purdy

Underdog ADP: 103.2 (QB11)

George Kittle

Underdog ADP: 39.8 (TE3)

Jauan Jennings

Underdog ADP: 61.6 (WR34)

Isaac Guerendo

Underdog ADP: 143.5 (RB46)

The 49ers suffered the largest projected loss of offensive points due to injuries in 2024, and experienced the 3rd-highest defensive roster turnover rate this offseason. A combination of the 49ers' offense returning to health, while having the easiest strength of schedule in the league (with expected defensive regression), should lead to an abundance of high-scoring shootouts.

Weekly safety paired with consistent upside has been the standard for Brock Purdy so far in his career. Over the last two years, Purdy has recorded the 5th-most games of 18.0+ UD-points, and the 6th-most games of 24.0+ UD-points. Those marks are higher than either Kyler Murray or Patrick Mahomes, who are both going at least a full round earlier than Purdy in best ball drafts.

The best QB/TE stack (at cost) in 2025 is undoubtedly Purdy and George Kittle. No TE has been more valuable in best ball leagues over the last two years than Kittle. Over that span, Kittle leads all TEs in weekly performances of 10.0+ UD-points (19), 14.0+ UD-points (14), & 18.0+ UD-points (7).

Kittle was also the most dominant TE when healthy last season, ranking first in FPG (13.2), FP/RR (0.51), and performances of 14.0+ UD-points (8). Those marks ranked 15th-best, 6th-best, & 5th-best among all receivers, and are better than DK Metcalf, DJ Moore, or Xavier Worthy recorded (who are all being drafted ahead of Kittle). With Deebo Samuel gone, and Aiyuk likely to miss the first several weeks of the season, there are very few players who are going in the 4th round or later of best ball drafts who will have the upside that Kittle has.

I’m also enticed by the value we’re being offered with Jauan Jennings falling to the 6th round or later. I’ve outlined the reasons why Jennings’ “5th-year breakout” could easily be repeated in a previous article, and I’d go as far as saying that he’ll be even more impactful in best ball tournaments in 2025. Jennings was one of only 11 receivers to record multiple games with 24.0+ UD-points last season, and his 41.0 UD-point performance in Week 3 was the 5th-highest scoring week for any non-QB last season (a game in which Samuel was out). Jennings may do most of his damage while Aiyuk remains sidelined, but the season-long upside is worth chasing at the price we’re currently being offered.

If Jennings and the 49ers are unable to agree on an extension, Ricky Pearsall is well worth targeting. He currently has a 7th-round ADP (WR41), and has shown the ability to produce high-scoring fantasy weeks. Pearsall recorded performances of 24.7 UD-points and 15.9 UD-points in the final two weeks of the 2024 season when Aiyuk was sidelined.

If you have a high risk tolerance, Christian McCaffrey is consistently dropping to the end of the 1st round. However, given that McCaffrey has twice the in-season injury risk as the average RB, I am drafting Isaac Guerendo as often as I can. Guerendo averaged 4.70 YPC, a 7.4% explosive run rate, 0.26 MTF/Att, and 16.2 FPG in games where he played over half of the snaps. Those marks would rank 12th-best, 4th-best, 3rd-best, and 8th-best over a full season. He also has receiving upside comparable to that of McCaffrey if utilized in a similar capacity.

This 49ers team stack comes at a price comparable to last season, and a favorable playoff schedule, as they’ll face the Titans, Colts, and Bears in Weeks 15-17.
