Despite all his injuries is porzingas the best health outcome
Now for a 7’3 player? I guess mark Eaton stayed relatively healthy.
Kareem and Artis Gilmore had solid careers at just an inch shorter.
The guys over 7’3” that I remember were Shawn Bradley, Ralph Sampson, Mark Eaton, Rik Smits, Yao Ming and Manute Bol.
Sampson started out looking like Kareem but quickly trailed off after some injuries. Bradley and Bol were not stars and were both too fragile or unskilled to play a lot of minutes.
Eaton and Ming were both giants. Zach Edey coming out from Purdue is in that same range.
Smits had a nice jumper, so possibly the only one that would fit in the modern era. I think Sampson probably could. I think he had the athletic ability to play today, but would need to augment his skills. Playing more of an outside role might have improved his longevity by not having to bang under the hoop at 7’4” and 225lbs.
Smits, Ming and a lot of other 7 footers have had foot problems that required surgery. That seems like a common problem that cuts careers short.
