It's a good argument you make. But where it's flawed is that Travis's era of drafting is only JC through AJ drafts. All past samples are not comparable because the Hawks didn't draft that well in the past. Babcock, ASG, Sund, Ferry, BudCox.... all terrible drafters.
Best players we drafted were Smoove and Horf as far as the 2000s go, until recent.
And yes, I'm against a trade for Siakam if it includes any of AJ/JJ/OO.
I am all for trading out Dre and Clint for an upgrade to allow more opportunity to the above.
