I found this video on YouTube of an interview with Donald Thomas. He is very confident, as he introduces himself as "Donald Thomas, STARTING right guard for the Miami Dolphins." Hopefully he can get back healthy and earn that starting right guard spot. Nothing is, or should be guaranteed for him. He has only started one NFL game, so he just won't be handed the job. Also, said he expects nothing less then a Super Bowl year.
