Smaller guys like Kyrie and IT get injured more often. That is why I would not resign him.
There is absolutely zero proof, zero facts, zero studies that this is true in any professional sport. Injuries happen to big players and small players alike in all sports. If what you said was true, small people simply would not be playing sports because professional sports GMs would have that data and never sign small players.
Zero proof? Kyrie? IT? Both missed the playoffs due to injury.
Plus, how many championships have been won by teams whose best player was under 6'4"?
Bill Walton and Yao Ming were bigs that had injury shortened careers, what's your point.
Off the top of my head, Detroit with Thomas, and GS with Curry jump to mind. Its arguable whether Lew Alcindor or Oscar Robertson was the best player for the bucks. MJ was listed at 6-6 who was a non-big, that was the best player on championship teams, Kobe also. Edit: I also forgot DJ for the Sonics
Thanks for proving my point.
Jordan, Lebron, Duncan, Kobe, Shaq, Bird, Magic, Jabbar, Wilt, Russell, Willis Reed, Bill Walton, Olajuwon, Nowitzki, Durant, etc...the vast majority of NBA championships have been won by teams where the best player was over 6'4".
In fact, in the last forty years there have only been six Finals MVPs 6'4" or under.
