Irrelevant to the current trade, but the precedent of top-5 fantasy players is a bit more than those deals.
LBJ is 34 years old and at the time of the trade, Kawhi was coming of a 9 games played season so was a huge question mark.
In terms of top-5 fantasy players being dealt, we've had 2 over the past month:
http://www.profsl.com/smf/index.php?topic=349205.0Return = Ben Simmons + 2 1st Round Picks
http://www.profsl.com/smf/index.php?topic=350122.0Return = John Wall + Donovan Mitchell
No one in this trade for KD is close to Simmons or Wall, (or Mitchell for that matter), with all respect to Ingram. He's nice, but isn't a stud fantasy player and I don't see him ever being one. His stats have actually regressed a little bit from last season, even with the recent surge from Lebron being out.
