Adams agreed to a two-year deal Tuesday and, shortly thereafter, took to Twitter to make the announcement.
To say the Colts had to re-sign Adams would be an understatement. The Colts cut LaRon Landry last month, and Sergio Brown signed with the Jacksonville Jaguars.
Adams went from being pushed to the curb by the Denver Broncos last year to sitting at home waiting until the middle of June for a team to call him to becoming the Colts' starting safety to making his first Pro Bowl.
Adams ended the season with 87 tackles, 11 passes defended and seven takeaways, the last of which was tied for second in the NFL.
The Colts need to find another starting safety, but re-signing Adams puts them in position to have three of their four starting defensive backs returning next season. Indianapolis also signed its third cornerback, Darius Butler, to a contract extension this past weekend.
