Best Ball Drafting Backup QBs: How to Build Your Quarterback Depth in Best Ball
Why QB depth strategy in best ball differs from season-long formats: in a season-long redraft league, you set your lineup each week and stream QBs based on matchup; depth matters but you have the flexibility to drop and add. In best ball, your scores are automatically maximized from your roster — there are no weekly adds. The QB you draft is the QB you have. If your starter has a 12-point game, your best ball roster needs a second QB with at least 20 points to provide the positional production your roster is optimized for.
Drafting Backup QBs in Best Ball
The two QB draft strategies in best ball:
The frameworks: (1) the elite QB anchor strategy — draft one top-5 QB in rounds 2–4; then grab a mid-tier QB with upside in rounds 10–12 to back him up; your anchor covers most weeks; the backup only starts when the anchor has a bad week; (2) the two-QB ceiling strategy — draft two mid-tier QBs (rounds 7–10) who each have high-ceiling weeks when their circumstances are right (big game, good matchup, home favorite); your best week from either QB is the score that counts; this strategy requires finding two QBs whose good weeks do not tend to correlate (one indoor team QB + one good-matchup outdoor QB); (3) the best ball scoring structure determines which is better: in half-PPR or full-PPR, running back and receiver points dominate; QB points are high but not dominant; the two-mid-tier approach is often more roster-efficient because it frees up an early pick; in superflex (where you start two QBs), elite QB value is multiplied and the anchor strategy at both QB positions is necessary.
The profiles of valuable late-round backup QBs:
The criteria: (1) high upside ceiling — a backup QB who can put up 30+ points when healthy and in a good matchup; a backup who is capped at 24 points in a great week is not providing much coverage over a starter’s average week; (2) predictable usage — a backup QB who starts consistently (not in a weekly competition) provides more reliable coverage than one who may or may not play; (3) high-volume passing offense — a QB on a team that passes 40+ times per game has more per-game ceiling than one on a balanced offense; (4) the emerging starter — a rookie or second-year QB who takes the starting job before the season (or earns it in the early weeks); their ADP may be late-round as a “backup” but their actual opportunity becomes that of a starter.
How to sequence QB picks in best ball:
The execution: (1) wait on QB in 1QB formats until round 7 at the earliest unless a top-5 QB falls significantly; (2) take your backup QB 4–6 rounds after your starter; do not stack two QBs in the same rounds; (3) use TE late-round upside thinking when evaluating late QBs — the same “emergent role” profile that creates TE breakouts creates QB breakouts; (4) combine QB depth with the overall best ball draft strategy hub framework — QB is the position most affected by the total roster structure; a roster heavy in WR/TE upside may need less QB depth because the other positions carry the scoring; one heavy in RBs needs more QB upside to compensate for the lower per-position ceiling.
