Former Arizona Cardinal football player Luis Sharpe has been arrested again, this time on drug possession charges.  Police spokeswoman Shawn Sanders says officers were called Tuesday night to a Scottsdale, Arizona hotel.  Sharpe already had two outstanding bench warrants against him.  Court records show he failed to show up for preliminary hearings on August 13th and 16th for two separate criminal cases.  His 23-year-old daughter was found shot to death in June.
