LAS VEGAS - At 34-year-old, Shawn Porter (31-3-1) knows his career is closer to the end than it is to the beginning.

The former world champion takes on Terence Crawford (37-0) on Saturday night at the Mandalay Bay Resort and Casino.  The pay-per-view event will be distributed by ESPN+.

Porter will have faced almost all of the top fighters in the welterweight division.  The results have been mixed as he holds victories over Danny Garcia, Yordenis Ugas and Andre Berto, while having also lost decisions to Errol Spence, Keith Thurman and Kell Brook.

While discussing the fight against Crawford, Porter was asked about the legacy he will leave in the sport.  He said that he is proud of what he has accomplished but wants to achieve more so that when his name is mentioned, people won't say he was a great champion "but" he lost to so and so.  He doesn't want there to be any "buts" associated with his name.

"I think the first part of my legacy is done. You can say that Shawn Porter has fought everybody. The other side of the legacy is I need y'all to say that Shawn Porter was in the ring with the best and he beat some of the best. This is the other best and I have to beat this dude. I keep saying that I have been in a couple of Super Bowls. I have won some and lost some but I don't want this to be a Dan Marino effect when you are all talking about how good or great Dan Marino was but he never a Super Bowl. I can't have y'all saying that about me. I can 't have you all saying he was in the ring with the best 'but'. F' that 'but'," said Porter.

Crawford's mean streak and finishing ability has been mentioned through out the lead up to the fight while Porter is known as being a nice guy.  Porter said not to let his smile fool you and that he also has a mean streak but that he shows it differently.

"It comes in a different package in this fight. The package I have works for me and the package he has works for him. It is up to me to make my package work for me against him and that is what I intend to do," Porter explained.
