Former 2x Heavyweight Champ Unretires

Former 2x World Heavyweight Champion Chris Byrd at 50 years old took to social media to show off his body transformation from heavyweight to middleweight!? by watching the clip below he shows off his speed and calls out the middleweight division.

He joins the list of former retired boxers claiming to be ready to get back inside the ring following Tyson, Roy Jones Jr, Oscar De La Hoya and Julio Cesar Chavez (Who wants to fight De La Hoya)

What is your thoughts on the old timers coming out of retirement? Can Byrd even compete in a stacked middleweight division that has Gennady Golovkin, Canelo Alvarez let alone guys like David Lemiuex or Jermall Charlo? What would be the realistic expectations?
