Acquiring KAT would be amazing. Having Brown as your 3rd best player makes this team a contender imo.
Actually, if it came down to it, I would still do the trade if it meant Brown+pick+filler for KAT+starting (non-allstar) level point guard in a multi-team trade. (A point guard like idk, Brunson? Rozier? Dinwiddie? Guys who have the talent to start but aren’t at the level of ‘fringe allstar snub’ the way Brown is)
So for example, we could have a line up of Rozier/Smart/Tatum/KAT/TL
or alternatively, xx/Brown/Tatum/KAT/xx
Both are great lineups imo with the first one being more defensively versatile and the second one being more top heavy, ala BKN.
