Yes, I could understand that but i wonder on the basis of that. Just because Duncan and Manu are injured last season? Those who are injuried can recover to play the whole season. Just look at Grant Hill, Vince Carter who has played nearly all the game last season despite having health issues earlier in the career)
If his basis is on age, Kobe is also on the 30s, along with Garnett, Shaq, Ray Allen, Carter, etc.
Anyway, just wish to point on the assumptions that he had made to make his prediction may not be correct.
