UCLA, with quality wins against Maryland and Michigan State last week,  grabbed the top spot in the ESPN/USA Today coaches' poll today, reports the Los Angeles Times, while North Carolina retained the No. 1 rank from the AP. Overall, the Top 25 saw numerous changes with 13 ranked teams losing a game last week. Injuries, though, haven't slowed the unbeaten Bruins.
                                    
                                    
                                
                                
                             
                            
                            
                            
                            
                            
                                
                                
                                    
                                        They're 6-0 despite starting power forward Alfred Aboya's facial injury and All-American guard Darren Collison having not played yet  this season. UCLA plays No. 8 Texas on Sunday in the Pac 10/Big-12 challenge. Memphis, Kansas and Georgetown round out the top five in both polls. Southern Cal, which upset Southern Illinois Sunday moved back into the Top 25.
