Some starters named:
Blaine Irby OR Greg Smith
Vondrell (Mack says he's running a 4.3) OR Chris O
Jordan Shipley (Mack seems really high on him right now)
A third receiver hasn't been identified yet
Colt McCoy (unless in the "q package")
Lamaar Houston OR Aaron Lewis at tackle
Brian Orakpo (no surprise there)
Aaron Lewis OR Henry Melton at stongside end
(Mack emphasizes that Lewis will start be it at one postion or another)
Rodderick Muckleroy OR Rashad Bobino
Rashad Bobino OR Jared Norton
Deon Beasley (although Mack seemed hesitant when talking about the CB's, sort of nonchalantly straying off topic)
Mack said Curtis Brown will definitely see playing time against FAU
Mack convieniently avoided the safety position, merely mentioning that they have a handful of fast talented guys who can all play.
Misc: Up to 10 true freshman could see the field this week. Mack also mentioned some tidbits about FAU.
I believe the Press conference is available on texassports, not sure, a transcript will be out no doubt.
