Wait, what?
I'm guessing you meant 7'3.5 for Dekker? If that's true they both have huge wingspans.
Wait, just looked it up. It was 83.5'' (as in 83 inches or just an inch under 7' wingspan).
Basically what I expected for Kaminsky. Dude has narrow shoulders, nothing surprising there to me. That is a pretty good number for Dekker though being at 6'11.5 wingspan, probably an inch or 2 more than I thought it would be.
That would indicate that Dekker is almost the same size as Marvin Williams or Dieng with the T-Wolves.
At that size he could play some stretch 4.
