This thread is not designed for loads of replies, just an answer. Both are champions who goes in first?
Ward has won every fight in the tournament and is ring magazine's number one rated fighter so I'd expect him to have the choice whether he comes in first or second.
One is making his 4th WBA defense after having taken the title outright from the #1 in the division at the time. The other is making his 2nd WBC defense, after winning a vacant title against a blown up middleweight. Obviously Ward walks out second.
One just fought Pascal, Taylor, Dirrell, Kessler, Abraham and Johnson back to back all over the world. The other just fought Shelby Pudwill, Kessler, Green, Bika then Abraham.. all in California. But I'm just messing I get your point
Given it's a tournament final, no matter who it is, or how they got there, it's not a typical challenger v champion scenario, it should be decided fairly, ie coin toss
