Even though this positions concerns me, it appears to be among the most improved positions on the KC Chiefs roster. Last year the Chiefs looked to have a good set of cornerbacks but then Stanford Routt ended up being a bust, throwing everything into a tailspin. That created a situation where cornerback was a liability.
With new blood this year -- notably Dunta Robinson and Sean Smith -- cornerback does not appear to be a major liability right now. Robinson is a long-time veteran so you think you know what you're getting in him. Smith is a little more boom-or-bust but his height and his coverage abilities should help.
Flowers will hold down one side; Robinson and Smith are competing at the other spot. That's three corners capable of starting. This position got better.
