The resurgence of the 3-4 defense in which a massive NT is essential to make it work, centers like Koppen who are just shy of 300 pounds may be an endangered species. Two-gap run stuffers like Ron Brace are coveted. People are already talking around here about Alabama's Mt. Cody for the Pats next year. This may be a harbinger of this season--Patriots run blocking--Koppen knocked back into the backfield to blowup a play. Defenses can expect runs off tackle more than up the gut with the exception of a draw during an anticipated pass. So I had my expectations dashed that the Patriots were going to draft a center in the 2009 draft. There were three goods ones: Eric Wood, Max Unger, and esp. Alex Mack. All three had an upgrade on size over Koppen. I wonder if Hochstein would be an improvement today.
