It's all about which young guys you draft. That's the important part. The Sixers have shown no ability to draft well. The Lakers did well I believe with Randle. Clarkson looks decent, but not sold. Russell has tons of upside, but that's going to take time.
The Lakers may have the prestige to just build a team through Free Agency, but almost all the championship teams in the last 20 years has had at least one home grown star to build around. Not sure if the Lakers have that.
The Lakers would have to gut the entire team as they have no one to build around. Assembling a team through Free Agency would be incredibly difficult because you couldn't just go out and sign the best players, you would have to assemble a team around a style of play and a focal point. You would have to combine certain big names if you're able to get them in the first place.
What he was talking about, which I don't think I made clear in my post, is trading one or all of Clarkson, Russell and Nance and also going after a top FA. The example he used was trading for Bradley Beal and Al Horford to play alongside Randle and using that roster to attract a top level FA or 2.
It should also be noted that none of what he was told came directly from the Lakers. He made sure to say that it's the feeling he gets from what he's heard.
