The St. Louis Rams will host former Chicago Bears fullback Jason McKie today, according to this report from Vaughn McClure (related to Troy?) of the Chicago Tribune.
Unlike Willie Parker who the Rams kicked the tires on as a potential backup for Steven Jackson, McKie does not fit that role. He's a fullback, a blocker, and we all know where those guys fit when Mike Martz is at the helm.
The Rams have FB Mike Karney, who signed a three-year contract last year as a free agent. An excellent blocker, Karney does have a bit of an injury history, missing two games last year and four the year before. Given that style of play, it's of little wonder. I wonder if the Rams are concerned about Karney's health?
