Also, lets get the facts straight here, Denver never needed Billups or a strong player from the PG position.
If they did, they would have just kept Andre Miller instead of trading him away for AI.
What the Nuggets needed was another star player and improved play from every other Nugget not named Carmelo Anthony.
Melo's game also regressed playing along side Billups last season. His scoring and efficiency went down playing along side Chauncey.
The two seasons playing along side AI, Melo's scoring was higher, his shooting efficiency was drastically higher (20 to 40 points higher in cases of TS% or eFG%), and Melo's Per was over 21 in both seasons with AI at his side, only 19 with Billups last year.
Now, I am not saying that Billups was bad for Melo. The truth is, when we look deeper, is that the Nuggets last season had better play from the whole team, across the board. Melo didn't need to do a heck of a lot more than he did. The previous 2 seasons, Melo and AI had to carry the load because they weren't getting production for whatever reason (injury or younger guys just not getting it done).
