Brandon Flowers is not on this list because he is a bad player. Flowers has been a serviceable cornerback for the Chiefs, but he certainly has the ability to be better.
Even though he is a good defender and one of the better open field tacklers among cornerbacks in the league, he needs to come up with more takeaways as a cornerback.
Flowers has had only six interceptions in the last two seasons. In 2010, Flowers had an interception in Week 2 and Week 3 but never recorded another one in the season. In 2011, he had only four picks but helped the Chiefs in field position as he finished 12th in return yards off interceptions.
After the season opener in 2011, Pioli signed Flowers to a five-year contract extension worth $50 million.
Flowers has one of the most dangerous pass-rushers in Tamba Hali, and Justin Houston improved in the second half of the season. If those two continue to cause problems for quarterbacks in the pocket, Flowers could come up with more interceptions with some ill-advised passes thrown his way.
Now that he is making big money, it should be expected of him to make more plays as a defender.
