Brandon Flowers announces his retirement

CB Brandon Flowers announced his retirement this morning via Instagram. The 31-year old spent his entire nine-year career with the Kansas City Chiefs and the San Diego Chargers, leading all CBs with a 90.1 overall grade as a member of the Chiefs in 2010.
Flowers ranked within the top-10 among cornerbacks in terms of overall grade for four straight seasons from 2009-2012. During that stretch he held opposing quarterbacks to just a 71.2 quarterback rating on 361 attempts into his coverage; he intercepted 14 passes over that span while breaking up an additional 37 passes.
In his magical 2010 season, Flowers ranked seventh among cornerbacks by allowing a 65.0 passer rating into his coverage; he was the only cornerback out of the 100 who qualified to not miss a tackle in the passing game (he missed just one tackle all season period, leading cornerbacks with a 65.0 tackle efficiency rating); and he ranked 11^th with a 2.5 run stop percentage.
