I'd say, accurately, that we were the 3rd fastest to finish the race, and that's what counts. They don't give out medals to the leaders at the halfway or 2/3 way points. You place where you finish, not where you should have or could have finished.
I'd also advise against betting your hard earned money on players that are prone to run out in front of moving traffic. One advantage of a young team is fewer games missed due to injuries. Injury prone players don't help you win when they are sitting behind the bench in a suit.
You add a 33-year old Paul Millsap to your roster and expect him to perform like he did when he was 30, or even 32, you're setting yourself up to be disappointed. While injuries can happen to anyone, no one should be surprised that guys like Millsap missed time due to injury. Gobert isn't old, but he has missed significant parts of 3 of his 5 seasons in the league. Again, it should not come as a surprise that he missed a significant number of games last year. It's par for the course.
These preseason projection assume everyone will be healthy and perform near their career averages. Injuries are unpredictable, but you shouldn't just assume everyone will be healthy for 82 games. To me, it would make sense to weight player projects based on age and past injury history. It's not a perfect formula, but I think it would be more accurate than just assuming equal health for all 30 teams.
