Berto ain't' a bum to me, he's an athletically flawed fighter with speed and power with slightly below average boxing skills.  Plus he has a tender chin.  Historically guys, like that will always get in entertaining scraps and get more chances than they deserve.  It happens, so I try to embrace it sometimes.
He would have been a name tune up that brought in good ratings against Swift.  I also think he would have put up a decent effort, ultimately losing though.  That fight not happening, made 2 lesser fights happen in Swift vs that bum he just fought, and now Berto vs Algieri if that goes through.
