They traded for Corbett 2 days after LG Joe Noteboom went down (week 6). They had 9 OL on the active roster and Brewer was on the practice squad at the time. OT's Whitworth, Evans, Havenstein. OG's Noteboom, Blythe, Edwards and Demby. C's Allen and Shelton. Was it Allen was so bad they traded for an OG to take his place at C or was it because they had a starting OG go down 2 days earlier? Edwards went in for Noteboom in game 7, after Demby finished the week 6 game. In week 9 (Pittsburgh) both Allen and Havenstein went down. Blythe went to center. Corbett started at LG and Edwards moved from LG to RG. Evans went to RT for Havenstein. Brewer came off the practice squad and Demby was inactive (often). With 1 guard injured (Noteboom), 1 guard moved to C (Blythe) and Demby being unable to hold down a backup spot, they ended with OT's Whitworth, Evans, Brewer and Havenstein (who was not IR'd with hopes he could return). OGs Edwards, Corbett and Demby. C's Blythe, Shelton. If they began cross training Corbett, that's their M.O. but he played OG once Allen went down. I think it might have been "maybe Corbett can play center, let's see what he has" but he was a starting G by week 10. I think some fans might be right in thinking it's Shelton or Anchrum and/or a draft pick at C. Given Anchrum's skillset, intelligence and heft, I hope he can play center.
