#1 David Haye got knocked down vs Monte Barrett

#2 Walker would KO David Haye

#3 Cris Arreola is a proven fighter at heavyweight and David Haye is not as he has had only 2 fights at heavyweight both were far from spectacular and they had him matched vs very weak opponents

#4 Wladimir beat Monte Barrett when (and if) it ever meant anything....and Wlad didn't get knocked down in the process either

I honestly don't care who Wladimir fights next because he'll beat either of them.
