Hawks: Trae Young, Jalen Johnson the only untouchables in potential trade talks?

Young is an offensive maestro with clear defensive weaknesses that must be masked by the rest of the roster, but the 2021 run showed how this is possible. Johnson is a rising force who is still under a team-friendly rookie contract for another season and is the other obvious keeper. After that, everything should be on the table, and league sources say that is indeed the case. (My spies say the Hawks also have described rookie guard Kobe Bufkin as untouchable, but would they walk away from a deal over him?)
