You aren't going to get a "franchise guy" in free agency, but the four names above can keep the seat warm. Vick showed last season he still has wheels. ... Cassel struggles with pressure, but he can push the ball down the field and is the safest pick of this group. ... I'd be worried about McCown backsliding if he leaves coach Marc Trestman's loving arms. ... Freeman is ranked third because he's only 26 and could still develop into a long-term answer if everything broke right.
