I know that Pastorini, Robert Brazile, Earl Campbell, and Elvin Bethea follow the Texans.
I met Haywood Jeffries last season. He comes to the games too however he admitted to me that "it is not the same", so I did not see him too excited about the Texans.
The sad thing is many of the old Oilers feel lost/forgotten because they are associated with a team that no longer exists.
