Cover 3 Buzz
Backer buzzes · secondary stays deep
Cover 3 where an underneath defender — usually the SAM or nickel — buzzes out to the curl/flat instead of a rotating safety or corner. The secondary stays 3-deep across.
When it applies
When you want the curl covered without rotating the secondary — the buzz defender can play run first, then drop.
+ StrengthsNo rotation to read pre-snap; the buzz defender is live against run and short pass.
− Trade-offsThe buzz has the longest drop — good quarterbacks throw the curl before he gets there.
