The boring answer is usually the useful answer
Most start/sit mistakes come from treating every new quote, practice clip, or analyst take like it should reset the board. It usually should not. A useful start/sit process starts with the player role, then checks whether the newest information is strong enough to change that role.
That is the product philosophy behind FantasyPizza too: rankings and player validity should come from deterministic data, while the assistant should explain the decision in plain language.
Use tiers before vibes
Before asking whether one player feels safer than another, place them in tiers. If the players are in different tiers, the higher tier usually wins unless there is a concrete role, injury, weather, or matchup reason to move away.
If the players are in the same tier, then the context matters more. That is where target share, route participation, red-zone work, team total, defensive matchup, and injury freshness can break the tie.
Know what would change your mind
The best fantasy managers decide what kind of news actually matters before the panic starts. A limited Wednesday practice is not the same thing as a surprise inactive report. A coach compliment is not the same thing as a role change that shows up in snaps.
A good assistant should say this out loud: the recommendation, the confidence level, and what update would make the answer stale.
