Vikings coach Brad Childress is the typical tight-lipped NFL coach, but he opened up on a radio interview last weekend. And Childress revealed an apparently tense conversation he had with Patriots coach Bill Belichick about a couple of players each team wanted to pass through waivers and put on the practice squad. Childress said Belichick called to ask him not to claim tight end Garrett Mills, offering to avoid picking up a player the Vikings cut as a reward. Childress declined. "He didn't really care for that," Childress said Sunday morning on WCCO-AM. "He was trying to leverage, but you always find out who is honest and straightforward." So the Vikings claimed Mills, the Patriots claimed linebacker David Herron, and Childress later realized he said too much.
