Nolan out as 49ers head coach?

According to ESPN's Michael Smith, the 49ers will fire head coach Mike Nolan after Sunday's game against the Seahawks. The Niners were 2-1 but have lost their last five games. Here's what I don't understand: Why not just fire the guy now? In the NFL, if you fire the coach during the season, you're basically giving up all hope of the playoffs, so why not toss the reigns to someone else right now? All this does is create an awful, awkward working environment for all involved. One more question I have, How come all these coaches get fired but Herm Edwards continues to fly under the radar as one of the most overrated coaches ever?Check out more from Tony Arnoldine at http://tixytixy.blogspot.com
