The Browns are getting tired of the drama surrounding Peyton Hillis and they are prepared to let him walk in free agency after the 2011 season, according to sources. At this point it would take a dramatic turnaround in behavior and production for Cleveland to re-sign him when he hits the open market in March. "It's one thing after another, and what's been out there isn't even the half of it," one source said. Hillis is expected to miss at least a couple of more games after re-injuring his hamstring in practice Friday afternoon.
