San Francisco coach Mike Singletary plans to send the NFL a lengthy list of grievances following Sunday's loss to Seattle. Singletary sends a letter to the league every week, but he said this one will contain "many" examples of what he thought to be questionable calls in Sunday's contest. "Every week we send a letter to the league about different calls that are made, or not made," he said in his Monday news conference. "This week there will be several paragraphs going to the league. ... Obviously, there were bad calls made yesterday. ... There were a few more than I have witnessed maybe since I've been in the league."
