A fight between them would certainly generate a large amount of hype and possibly a good fight purse for both men.However, should a fight between them fail to materialize then they both have a number of options ahead of them. Tony Ferguson could be a reasonable matchup for either man, and he has already expressed a willingness to move back up to 170 lb, which would certainly suit Diaz.UFC 262: Tony Ferguson v Beneil DariushAlternatively, Diaz could be holding out for a trilogy fight with Conor McGregor. Both men have a win apiece and are at a point in their careers where revitalizing the old rivalry could do wonders for their public image.Should Dustin Poirier wish to remain at lightweight then a bout against Michael Chandler would certainly be a thrilling proposition. If he wishes to move up to welterweight then Colby Covington would appear to be the logical choice, given their intense dislike for each other.UFC 268: Usman v Covington 2
