April 18 marks the 18th anniversary of the Colts drafting No. 18, Peyton Manning.

In 14 years with Indianapolis, Manning became known as much for his pre-snap commands as for his touchdown strikes. This 2007 NFL Films video breaks down how Manning became such a master of the audible. 

Revisit a time when Peyton Manning wasn't so mature

Manning's directions at the line of scrimmage were a big reason the Colts made 11 playoff appearances and won 12 or more games in seven straight years. 

This segment was included as a DVD extra on the commemorative video released after the Colts won Super Bowl XLI, their first championship since 1970. It's funny to hear Manning's precursors to the "Omaha" call that he made famous last year ("Short ox! Short ox! Richmond, Florida, Buffalo!"), but it's also fascinating to hear him and his linemen explain the process. It is not, as ESPN's Kenny Mayne once posited, a rare form of Gaelic.
