The fun thing about this game is trying to imagine how much better players become when they are surrounded with different and sometimes better casts of talent. Carmelo Anthony is the prime example of a player who would play much better with a great surrounding cast he never really got in the NBA. Shaq would probably be more effective if he played with a PF that could spread the floor and a PG that could deliver perfect passes.
Here's some thoughts I have on players in this matchup and how their game would translate on to their new teams.
Nash I feel would play very similarly to how he played on the Suns teams. This team has similar floor spacing, maybe a slightly worse p&r partner, but even though Nash could be relied on to carry all the offense every possession, he won't have to bear that burden here, which is nice at times. Overall, it all evens out to me.
Allan Houston might be slightly more efficient due to just less reliance on him, similar to Ray Allen and Pierce saw increases in efficiency when they didn't command all the defense's attention.
When Durant left OKC, he improved a bit with the floor spacing in GSW and additional efficient offensive threats. The Boston team mimics that so I think he'd look very similarly offensively on this squad to how he did in GSW.
I think the Gasols would be slightly enhanced versions of the NBA versions of themselves because of the strong chemistry they'd have together. Both high IQ players with solid passing abilities.
I think Giannis would look a little worse offensively. The 4-around-Giannis offense in Milwaukee is perfect for Giannis to play to his strengths. This paint would certainly be more crowded than that, no matter how much Roy tries to say otherwise. The affect of that is certainly in question though and I really liked Roy's post about how star players for decades have been crushing it with crowded paints. I just think it has to be acknowledged that the 4-around-Giannis offense does allow Giannis to be at his best, so there would be some affect. People might be overstating that affect though. One thing Giannis has working for him is teams will be forced to play smaller defenders on him, which he will outmuscle on his way to the basket. The Celtics for example gameplanned ways to put their center Horford on Giannis because they could hide smaller PFs on Brook Lopez or Mirotic. It could be trouble for teams to pull a PF/C off of Malone or Zo and try to hide a SF on one of them. All things considered, I'd put Giannis at slightly less effective.
Malone I'd consider slightly less effective because he isn't paired with an elite p&r point guard. Conley is good, very good, I was in awe of his play that postseason, but he's not an elite p&r point guard.
Speaking of Conley, I feel like his performance that postseason (only because that was most of the games of his I watched that season) was so translatable to any team and situation. I think he'd perform pretty similarly here.
I think most people recognize Ginobili is a guy who benefited greatly from being drafted into an already strong team. He gets to play with a strong team here as well, which I imagine serves him just as well.
Zo is a pretty translatable player, but I think he would benefit from playing with multiple very good passers.
