Durant gives charge to the Thunder

ESPN Playbook

Injuries have plagued the Thunder and Bulls this postseason, so that means it's time for players to step up their game. Kevin Durant did just that after Russell Westbrook went down with a knee injury. KD's player efficiency rating skyrocketed from 20.8 with Westbrook on the floor to 31.6 without. Yup -- that's a 61.5 percent increase. Joakim Noah did the same for Chicago. Now he's not known as the scorer that Durant is, but Noah is showing he can put the ball in the basket quite often while also rebounding, dishing assists, blocking shots, getting steals and defending Derrick Rose to the media.

Filling out the top five was a mixture of athletes from different sports. Floyd Mayweather Jr. landed 60 percent of his power punches and kept his undefeated record intact (44-0, 26 KO) which landed him in the No. 3 position. Lionel Messi kicked his way to the No. 4 spot by extending his record with goals in 21 straight league games. Rounding out the top 5 was Orb for winning the 139th running of the Kentucky Derby in exciting fashion. Do you agree with our experts' rankings?
