Rookies to watch in the preseason

Miami center Samson Satele -- The 60th player selected, Satele is expected to have more of an impact this season than wide receiver Ted Ginn Jr. and quarterback John Beck, Miami's two higher profile selections. Satele is expected to be the Dolphins' starting center on opening day and, if the organization is right, he could be the centerpiece of the offensive line for the next dozen years. Satele is smart, tough and driven and he already is making calls for the entire offensive line. Satele has short arms -- not ideal for an offensive lineman -- but he is long on potential.
