Breh you can say that about any star from age era prior to the 3 point takeover as all teams had much worse spacing before everyone was capable of shooting 3's. Imagine prime Duncan on that 2013-2014 Spurs team.
Imagine what Magic could have done when surrounded by a bunch of shooters. Actually it's probably similar to what Lebron is doing offensively except with less scoring and more assists.
One thing that I think is dumb is that no one really takes into account that players from previous eras would have played differently in this era. They wouldn't just be the same quality of player as the game has changed, practices have changed, technology has changed, and development has changed significantly. You can show me what Bird averaged in the 80's for 3 point shooting and tell me he wouldn't be shyt in today's league, but if he was brought up in today's league I think it's fair to assume his 3 point game would have been far more fine tuned. A lot of post players from the past would have also probably developed 3's, like many bigs in today's league did. If Pau/David Lee/Ibaka can develop 3 point shots I think it's fair to say that others from the past could as well with the proper technique, development, and practice.
