Jim Thorpe (Superior multi-sport athlete)
Wilt Chamberlain (Great for bball and volleball and jumping T&F events)
Bo Jackson (Baseball hitter & fielder, football RB, athlete)
Tim Duncan (Basketball and swimming)
Jeff Samardzija (pitching huge in baseball, plus a quality WR and his dad was a semi-pro hockey player)
Deion Sanders (football and baseball, sprinter)
Herschel Walker (FB, wrestling and boxing)
Jeremy Yablonski (Canadian hockey pro and Gold Gloves champion)
Peter Zezel (played in NHL and some pro soccer)
Charlie Ward (Heisman QB, NBA pro and avid tennis player)
I think I covered every sport at list a bit except for handball.
Would have a heck of a football team, very good basketball and T&F, decent baseball and then some athletes for the other sports with at least one person of proficiency.
