Huh?
Cousins was the last Kings player to make an all-star team (he made four, two with the Kings and two with the Pelicans) and twice was on the all-NBA 2nd team while in Sacramento. He was in line for a super max contract until he had another meltdown and Vlade dealt him for Buddy and NOP's 1st.
I'm not comparing Boogie to Sengun but you seem to be moving the goalposts a lot in trying to find reasons not to draft him. Which is the only reason I find myself in the odd position of defending him. I've actually been a Jalen Johnson guy since before this last college season even started but all the chatter I'm hearing makes me think some of the red flags are significant. And that's on top of the holes in his actual game.
So I don't know who my favorite pick is at #9. But if it's Sengun I wouldn't be disappointed.
I think the only guys that would really disappoint me would be Giddey, Mitchell or a reach like Trey Murphy.
