The Pittsburgh Post Gazette announced today (http://www.post-gazette.com/pg/11327/1192078-100.stm) that LG Chris Kemoeatu has been demoted in favor of Doug Legursky. Kemoeatu's poor play of late is the reason cited for this.
It has become increasingly clear that "Big Juicy" is underplaying a 5 year 20 million dollar contract. Missed assignments, poor pass protection and a tendency for the occasional bone-headed fit of rage has made him one of the more up and down players on the team. While there is no doubting that he can deliver huge hits on pulls and traps and can be a really powerful run blocker, he never truly improved his mental game through his years as a starter.
This is probably the beginning of the end for him as a Steeler as the team is unlikely to carry his salary next year to ride the pine and will look to free agency or more likely to the draft to replace him.
