I would prefer Iverson over D-Rose talent wise. On a normal IRL team, I'd pick Iverson over Rose. Iverson was unstoppable. Rose was stoppable (as shown in playoffs against strong D).
On teams loaded with talent like these, I prefer Rose. I think he is easier to play with. Doesn't over-dribble as much / dominate the ball or flow of the offense as much. Plus, Rose is a much better defender.
I do have some offensive concerns with D-Rose (along with other high scoring guards with so-so jump-shots) but not as severe as my issues with Iverson.
My main issue with Iverson is how do you build a team around him? That is very hard. I can see D-Rose functioning in a few teams but Iverson is tougher. Despite the incredible talent that he has.
How do you create offensive balance and teamwork with Iverson ad-libbing / free-styling so much? Defensive balance is easy enough to accomplish. He just needs to defend PGs. But offensive balance is tricky.
What is the right offense to put around him? Both to allow AI to shine and to stop him from causing damage to / limiting the players around him?
Iverson had by far his two most efficient seasons (or season and a half) when he was playing with Carmelo Anthony. I think his inability to adapt or play in this type of situation has been unfairly criticized. when he was on a team with another great scorer, he shot less, took better shots, etc. and his efficiency went up significantly (he still got to the line and he actually shot a similar amount of 3 pointers he just made them at a much higher clip). Part of the reason his efficiency was so low for much of his career, is he was burdened with such an incredible offensive load and was basically the entire offensive focus. I mean he was the only even average scorer on the Sixers team he took the Finals (and basically all of those Sixer teams). The rotation in the Finals was downright awful offensively, as such AI had to do the heavy lifting. I mean seriously Mutombo might have been the 2nd best offensive player on that Finals team. Mutombo offensive player. I mean think about that.
I would put a lot of that offensive improvement down to the rules changing. The hand checking laws loosening up. That started in 2005 as Iverson was in the final years of his prime and it gave a glimpse of how much Iverson's scoring efficiency could improve in today's NBA which allows far less contact than the league did in 2005-2008 + has more spaced out offenses.
I do agree having more talented offensive teammates helped as well but the rule changes is a huge factor in my eyes.
I would say the hand-checking & physical defense - the pounding that opponents put on Iverson - was a huge factor in his low scoring efficiency. The era he played in. Compared to today's era where none of that can happen anymore.
--------------
When I look at Iverson's years in Denver, I look at those teams as dependent on (can't say his name yet - backup quality low usage starting PG). They needed this PG to play in order to make sure the big men were touching the ball often enough because Melo & Iverson would too often go into a "my turn / your turn" offense and ignore the bigs. Then the unhappy bigs was stop playing with the right level of effort on defense & on the boards. So they needed this PG out there to keep the bigs engaged and happy so that they would defend and rebound.
My lessons from this are:
(1) Don't put Iverson with another self-centered scorer. Combine him with a more team orientated scorer (Dirk) or facilitating big (KG).
(2) Make sure Iverson is not the PG. He needs to play SG on offense and PG on defense. So you need a versatile PG who is comfortable off the ball on offense and defending wings on defense.
-------------------------------
My main point of comparison for Iverson (in this Historical League) is his time with Team USA. I did not like how he played. He gave it everything he had - no questions of his commitment or intentions - but he simply did not know how to play on a team that did not revolve around him / let him do what he wanted.
He was a shadow of the player he was capable of being. He did not know what to do or when to do it. So many mental mistakes (on offense).
Not the incredible unstoppable star we had seen him be when he had his team revolve around his talents.
---------------------------
And this is the question for all the players in this league, how good can you be when your team no longer solely revolves around him?
How good are you when not in your best situation?
How adaptable / versatile is your game?
Not just Iverson. Everyone.
