Like it or not, Wladimir Klitschko may well be among the greatest heavyweight champions who has yet lived. If longevity and dominance over his era are any indicator, he should rank highly on many historian's lists. But because he's not American and because his knockouts are preceded by long stretches of clinical boxing his accomplishments haven't been embraced, especially in the U.S. But the numbers speak highly for him.
* His current seven year, five month reign is now second on the all-time list behind Joe Louis' 11 year 8 months. Larry Holmes, at seven years three months, is now third.
* He is now 21-2 (17 KO) in title competition.
* He hasn't lost a fight in nearly 10 years and has gone 18-0 (13 KO) in that time.
* His 14 consecutive defenses thus far ranks only behind Joe Louis (25) and Holmes (20) and if one adds his five WBO defenses between 2000 and 2003 his 19 ranks him third all-time, tied with Muhammad Ali's 19 in two reigns. Given the current crop it appears that "Dr. Steelhammer" can rule for as long as he pleases.
However, Klitschko is facing a test in WBA "regular" titlist Alexander Povetkin, who is undefeated in 26 fights and has been looking good as of late. Still, a Povetkin victory over the 37-year-old Klitschko would rank as a monstrous upset but stranger things have happened in boxing.
Statistical factors that may influence the outcome are:
