Now, that didn't take long. Minutes after announcing the release of Kamerion Wimbley, the Oakland Raiders announced the addition of Zone Blocker and Tough guy Extraordinaire, Mike Brisiel, formerly of the Houston Texans. (Interestingly, Brisiel also has experience as a Center)
This should come as no surprise, as BOTH Greg Knapp and new O-Line Coach Frank Pollack coached Mike Brisiel on the Houston Texans.
What may come as a surprise is that the Raiders lost some defense, which they are very thin at and added some offense. then again, from all accounts, Brisiel is a vey tough and high quality starter that will help the line transition to a zone blocking scheme.
