Does anyone out there have any information on the return of Phil Costa or Sean Lissemore? I know the season is over, but I would still like to see if Costa can man down the center spot and if Lissemore can get pressure starting with Hatcher and Ratliff. It would be really great if those players and Parnell could lock down spots. Dallas would still have to draft Oline hard, but if Costa was a solid center and Parnell was a solid RT it gives hope for next year. If Lissemore turns out to be a good player than the Dline would go from mediocre to good.
