What is Cover 1 in 5v5 flag football?
In 5v5 flag football Cover 1 puts four defenders on the four eligible receivers and the fifth in the deep middle, which means nobody rushes the quarterback. That is not an omission, it is arithmetic: five defenders against four receivers leaves exactly one spare man, and Cover 1 spends him on deep help. Sending him after the passer instead is a different call, and it leaves nothing behind.
Why Cover 1 works in 5v5
Covering everybody and rushing somebody are mutually exclusive
At seven or eleven a side you can rush and still have bodies left over to double a receiver or bracket a seam. At five you cannot. Four receivers take four defenders and there is one man left, so every defensive call in this format is one decision: does the spare play deep, or does he come? Cover 1 answers deep. Say that out loud to a team, because a coach who has not worked it out will keep asking why nobody is rushing.
The deep defender is the only help on the field
There is no second safety, no robber and no bracket. If a corner turns the wrong way, the man in the middle is the entire defense. Put your best open-field player there and tell him he helps nobody in particular and everybody in general, and that nothing gets behind him. At eleven a side a free safety can cheat toward a formation strength; here the field is too wide and he has too few friends to guess.
Nobody is holding a run, so man coverage is comfortable
Plain 5v5 has no offensive line and no center, and the quarterback starts with the ball, so there is no mesh point for a linebacker to read. Every defender can open and run at the snap. That makes man coverage far easier to play here than at eleven, where a backer reads run first and then chases a back into the flat having already lost a step.
Every receiver is somebody's problem
There are no seams and no soft spots to find, because nobody is guarding grass. A route that gets open has beaten a man rather than found a hole, which means the offense needs a player to win rather than a scheme to work. Against an opponent whose receivers are not better than your defenders, that is a very good trade.
It frees up extra rushers
Matching bodies uses exactly as many defenders as the offense has eligibles and no more. Everyone left over can come, which is why almost every pressure package in football is built on a Cover 1 shell. The quarterback is looking at man coverage and a count he cannot block at the same time.
The free safety erases one mistake
The single deep defender exists so that a beaten corner is a completion rather than a touchdown. That is the entire job, and it is why the coverage survives at every level: it accepts that somebody will lose and puts a player behind him whose only responsibility is to make it cost less.
Before and after the snap
The same call twice. What a coverage IS lives in the difference between these two pictures, not in either one of them.

Where everybody stands, and who is coming. This is all an offense sees before the ball moves, which is why a defense that tips its coverage from the alignment has given away the only thing it was hiding.

How to beat Cover 1 in 5v5
Cross two receivers and make defenders run into each other
Man defenders have to follow, and in a 2x2 empty set two receivers running opposite ways through the same ten yards cannot both be covered by men who are chasing. Run the two crossers at different depths, three yards and five, so your own players clear each other cleanly. That is the whole design of a scissors concept and it is the most reliable answer to this coverage at five a side.
Take the time nobody is taking away
With no rusher the quarterback has as long as the rules give him. A double move, a deep comeback, a receiver who stems inside and breaks back out: all of it is available in a way it never is against a four-man rush. Patience beats Cover 1 here more reliably than any particular route, which is exactly why the pressure calls exist in the first place.
What Cover 1 gives up
Traffic, rubs and crossers
Man defenders have to follow their receivers, so anything that puts two of them on a collision course wins without anyone beating anybody. Mesh, pick concepts and deep crossers are all designed to do exactly this, and they are the reason man coverage looks fine for a quarter and then gives up three straight completions.
A quarterback who runs
Everybody has a man and everybody has their back to the ball. If the quarterback pulls it down and goes, there is frequently nobody looking at him at all. This is the single biggest weakness of the shell and the reason a spy is the most common adjustment made to it.
