Is it possible for a 41 year old Pac-Man to fight and beat a prime Spence end of 2019/early 2020?

If he’s not retiring then why not go out with a bang?

Mayweather rematch is never happening.

Roach or Arum won’t let him fight Crawford.

No money in a Jeff Horn rematch..lol

Amir Khan could be a possibility?

What tactics or style will he need to beat a big welterweight in Spence..bearing in mind that Thurman, Garcia and Crawford have fought better opposition than Spence.
