Bottleneck defenders realize that the best way to stop a route is to act early. When they enter the zone, they are highly likely to dominantly win any man press encounter.

Defenders with this ability have higher chance to catch uncontested interceptions, and they have unlimited stamina on the return (until using a special move or breaking a tackle).

Defenders with this ability force more catch knockouts and react quicker in any flat zone coverage, less than 10 yards from the LoS and outside the hash marks.

Players with this ability are more likely to succeed at and attempt diving catches and swats.
