Naw, it won't be Kubiak or Zorn, both are West Coast Offense guys, an offense Joe Flacco cannot run. It won't be Norv; he's already under contract. Chudzinski might be a bet, but he's an abrasive personality and might buck against being controled by Harbaugh. Whomever the choice might be, there must be instant success or as Bisciotti said he'll step in next season and heads will roll.
