Flowers was drafted 35th overall in the 2008 draft by the Chiefs, becoming a solid answer for their secondary. During his time with the team, he compiled 374 tackles, 2 sacks, 4 forced fumbles, and 5 fumble recoveries. He also recorded 17 interceptions with 3 touchdowns. One of his highlight moments was a 91-yard interception off of QB Brett Favre against the New York Jets during his rookie season.
Things were not the same for Flowers as he started to decline physically with the Chargers. He only played all 16 games in a season once in his career in 2011 while with the Chiefs. After his departure from Kansas City, the CB would only play 31 games in three seasons with San Diego. 2016 was a difficult year, as he only played in 6 games and finished the season on IR after sustaining a concussion.
The Chargers cut Flowers before the March 7th deadline so that they could free up $7 million in cap space. From that point forward, it was difficult for Flowers to land a job with another team.
Flowers is one of the seasoned players that hung their cleats this off-season. His announcement is coming off the heels of a visit with the Arizona Cardinals, who signed Tramon Williams instead. He also received interest from the New England Patriots and Pittsburgh Steelers earlier in the offseason.
