In the wake of four straight losses, the Broncos are starting to crumble from within. Denver wide receiver Brandon Marshall says that he isn't sorry for yelling at rookie running back Knowshon Moreno on the sidelines following a fumble on Sunday. "We've got a lot of emotional players on our team. I'm an emotional person myself," coach Josh McDaniels said. "Sometimes that happens. I'm not saying it's good, as long as people can work things out. Obviously we don't want to make scenes or problems for ourselves on the sideline. But there are a lot of things that happen on the sideline that involve emotion."
