OK4 is NOT a 4
IF OK4 got schooled by Kaminksi, there is no way he can defend Blake Griffen, LA, many stretch 4's like Dirk/Bosh/AD/Ryan Anderson/Mirotic, and the SF/PF's like Lebron/Durant/Paul George/Draymond Green/Rudy Gay/Gallo etc...
I know you love height Briggs but height doesn't translate to a better team, you cannot say CA is a SG when he has trouble defending SF's and a reason why he plays better at a PF
Add in the weakness's of playing with CA and that is 2/5 spots, not even including our PG, which will likely be another weakness's to attack
He is much closer to a Center and that will even take time to work on his mobility/weight/strength
He cannot defend Al Horford/Millsap/ Carrolll or Pau Gasol and many other talents
Towns will have trouble defending stretch 4's himself who is much better on DEFENSE than OK4 but lacks the mobility to go out of the paint, especially at the NBA 3pt line, who is much better on DEFENSE than OK4
