Most cricketers lose their place when they stop performing. A wicketkeeper usually loses his when somebody else is ready, which makes his career follow an entirely different logic.
One position, no rotation
A side fields one keeper. There is no equivalent of resting a bowler or shuffling a batting order, so the incumbent plays nearly every match and the understudy plays almost none.
That produces a blocked queue. A capable second keeper can spend years accumulating no first-team cricket while remaining the obvious replacement, and his own development stalls the entire time.
Organisations manage this by loaning keepers out or by playing them as specialist batters. Neither substitute develops the actual skill, which only improves through keeping in real matches.
Selection is decided on the batting
Because keeping standards are hard to separate at the top level, selection arguments usually turn on runs. A keeper who scores keeps his place, and one who does not is replaced by someone who might.
This pushes keepers to develop as batters early, since that is the visible half of the job. Time spent on batting is time not spent on the specialist skill.
The consequence is a position evaluated mostly on the part of it that is easiest to count. Byes and missed chances are recorded; the hundreds of small positional decisions are not.
The physical demands are steady rather than spiky
Keeping does not produce the acute injuries that end bowling careers. It produces accumulated wear in the knees, back and hands from thousands of repetitions of the same crouch.
Hand injuries are the ones that interrupt a season, and they are difficult to protect against without compromising the technique. Players routinely keep through damage they would not bat through.
Because none of it is dramatic, the decline is gradual and easy to miss. A keeper is often the last person to notice that he has started standing up a fraction slower.
The transition out is unusually well signposted
Keepers move into coaching, captaincy and analysis more often than most positions, because the job has always involved watching everything and communicating constantly.
They also understand batting from behind the stumps, which makes them useful to scouting departments in ways that are recognised inside the sport.
None of that changes the awkward arithmetic. When the succession arrives, it arrives completely, and a keeper who was in the side one summer can be nowhere the next.
