Browns coach Pat Shurmur indicated Monday that he'll keep second-year pro Thad Lewis as his developmental third quarterback, meaning either Colt McCoy or Seneca Wallace will have to go. "There's something to Thad that I think is worth developing,'' said Shurmur, who coached Lewis in 2010 in St. Louis, where he spent most of the season on the practice squad. Shurmur was impressded with Lewis' ability to come in off the bench in the fourth quarter in Detroit and produce a touchdown and a field goal in his two drives. Shurmur acknowledged that his desire to hang onto Lewis will impact McCoy and Wallace. "Yeah, I think so,'' he said. "There’s no telling what's going to happen at this point. We’ve got a few days left here, close to 20, before we’ve got to make the final decision.†Source: Cleveland Plain Dealer
