Is it good or bad for sport that one individual or team dominates entire world? OR is it just passing phase?
(By the way these are the sports I follow, dont know how things are in other sports. Apart from these I also follow soccer but thankfully we see no one dominating really.)<div class="blogger-post-footer"></div>
