Heavyweight mini tournament is a good idea indeed, but honestly none of those fighters deserve a mandatory position. Easy work for Usyk/Joshua/Fury/any other future WBA Super champ.
Could expand it out to 8 ... with Oquendo, Lovejoy, Briggs and maybe Haye/John Ruiz for old time's sake.
In which case, he should fight Ivan Dychko for the prestigious WBA 'wasted prime' HW belt, previously held by Luis Ortiz.
Anything to get them fighting more regularly ! I know Covid has put a break on things to a degree, but if you want to fight you find a way. I remember thinking a while back, why hasn't it been done before.
