BBAO: Shuffle in Lions secondary

We're Black and Blue all over:

As you probably noticed, we opened the second week of NFC North training camps a bit out of order. Our first Monday post was the formal Green Bay Packers Camp Confidential, and now we're following up with our daily trek around the division. Hope we didn't throw anyone off. I don't often throw my changeup.

We start with the Detroit Lions, where starting cornerback Chris Houston was (temporarily, I presume) demoted to the second-team defense after receiver Calvin Johnson beat him for a big play Sunday. Defensive coordinator Gunther Cunningham barked at Houston, according to Carlos Monarrez of the Detroit Free Press, and put Eric King into Houston's spot. Dre Bly moved up to nickel.

As we discussed in the Lions Camp Confidential, Houston is drawing Johnson often in practice coverage. That's almost not fair. Based on what I saw, I would be really surprised if Houston isn't one of the Lions' starting cornerbacks Sept. 12 at Chicago. But it's clear that very few Lions players are guaranteed starting roles.
