Core 4: Ventrone right in mix

ORCHARD PARK, N.Y. -- The importance of special teams was reflected in the promotion of safety Ross Ventrone from the practice squad on Saturday. Ventrone was part of the four "core" units in Sunday's 34-31 loss to the Bills -- kickoff return, kickoff coverage, punt return, and punt coverage.

The same was true for rookie linebacker Jeff Tarpinian.
