The early issues with the 727 were related to unstabilized approaches, slow engine spool up speeds, and large amounts of drag when using flaps 40.
This was due to the engines used at the time, pilot training, and because the flaps (triple slot) were particularly draggy to keep the approach speed
low despite a very swept wing. Some airlines even prevented flaps 40 from being used, partially due to this issue.
Modern aircraft have similar approach speeds, but typically with far less wing sweep, far less complex flaps, leading to less drag. Training is also
much better. Actually plenty of airlines and airliners have monitoring equipment enabled, designed to catch pilots who repeatedly break standard
operating procedure, by for example, detecting unstabilized approaches. Typical parameters might be when during landing, the aircraft isn't in landing
configuration, the engines aren't spooled up, or excess vertical speed.
