The usual cause for something like this is that management is incentivizing for something that isn't quality. Velocity is the normal one that gets people, but there are a few others that occasionally get people (number of open tickets/lack of outrage on social media/etc).

It is, of course, possible that the team is incompetent, but that's usually an easier problem to fix, and if the team has had normal turnover, the odds of them having consistently incompetent ICs for years on end is pretty low.
