Matt Barkley to Wear Number 2 in Philadelphia

Rant Sports reports that new Philadelphia Eagles quarterback Matt Barkley will be wearing jersey number 2.  His familiar number 7, worn in college while at USC, is clearly not available with Michael Vick, currently starting at QB for Philly, occupying that number.  Barkley's high school number of 5, is also off-limits, due to its imminent retirement in honor of longtime Philly signal caller Donovan McNabb.  

Best Jersey Number Ever

What's the best jersey number of all time? Is it number seven, worn by Mickey Mantle and John Elway? Or is it number 23 worn by Michael Jordan and LeBron James? How about number four worn by Lou Gehrig and Bobby Orr? Number 33 could also be in consideration, worn by Larry Bird, Tony Dorsett and Kareem. And don't count out number three worn by babe Ruth, Allen Iversen, and Bronko Nagurski. But who would you pick? And what criteria would you use?
