The Soul have lost two ArenaBowls to the Arizona Rattlers, and now the team has lost to its best defensive back to the three-time defending league champions.

Four-time All-Arena defensive back Rayshaun Kizer has ended his tenure in Philadelphia and will join the Rattlers for the 2015 season, the Arena Football League announced Wednesday.

Kizer has spent the last three seasons in Philadelphia, two of which ended with trips to the ArenaBowl.

During his time with the team, Kizer caught 29 interceptions and recorded 264.5 tackles, including 101.5 during the 2014 season. He also scored five touchdowns. He earned All-Arena honors with the Soul in 2013 and 2014.

During the Soul's playoff loss to the Cleveland Gladiators, Kizer caught a league postseason record four interceptions.

Despite entering only his sixth season in the AFL, Kizer is statistically one of the best defensive backs in league history. He is currently third on the league's all-time interception list with 57, including a single-season league record 16 during his final season with the Orlando Predators in 2011.

As for the Rattlers, it's a case of the rich getting richer. Kizer joins an already formidable secondary that has been a key component during the team's dynastic run.

Kizer will be join a unit that already consists of Marquis Floyd, who led the AFL in interceptions last season with 13.
