DETROIT — While the Lions haven’t even played one preseason game yet, at least one person had Thanksgiving on his mind today when the Lions practiced at Ford Field in front of 15,387 fans.
   In his brief comments to the audience prior to practice coach Jim Schwartz talked about the tradition of the Lions playing at home every Thanksgiving.
  “Any time I hear somebody around the country talking about taking that game away from Detroit I will remind the commissioner about 15,000 (fans) standing in the rain for two hours to watch practice,’’ Schwartz explained afterward. “I think that says something about our fans  and I think it needs to be rewarded.’’
   NFL Commissioner Roger Goodell was in attendance and said there are no plans to take the Thanksgiving Day game away from Detroit.
